“I Can’t Handle This”: Why Discomfort Feels Harder to Endure Than It Is

/ Emotions, anxiety, Mental Health, Self-Awareness, Therapy / By

Discomfort is a thing to be endured. 

Waiting in traffic, struggling through a difficult task, sitting with an uncomfortable emotion, or staying in a tense conversation — none of this is pleasant, of course. Wanting relief by avoiding uncomfortable feelings is natural.

But for some people, the problem isn’t simply that discomfort is unpleasant.
It’s that it feels impossible to stay with.

You might recognise this in thoughts like, “I can’t stand this,” “This is too much,” or “I need this to stop right now.” These reactions often feel urgent and convincing, as though staying with the discomfort itself is no longer possible..

Let’s explore a psychological pattern known as frustration intolerance — not as a flaw or a lack of resilience, but as a learned way of interpreting discomfort. Understanding this pattern helps explain why emotional distress escalates so quickly, why avoidance feels irresistible, and how learning to tolerate discomfort (without liking it) can significantly reduce emotional distress.

What Frustration Intolerance Really Means

Frustration intolerance refers to the belief that discomfort, effort, delay, or emotional strain is unbearable — not merely unpleasant, but impossible to endure (Harrington, 2005b).

At its core, this belief is about tolerance. There is a meaningful difference between:

  • “I don’t like this,” and
  • “I cannot stay with this.”

The first allows room for coping. The second creates urgency.

In Rational Emotive Behaviour Therapy (REBT), frustration intolerance is understood as a belief about one’s capacity to endure discomfort, not a factual limit of strength or ability (Harrington, 2005b).

Research also highlights a striking paradox: people who believe they “can’t stand” a situation are often already standing it — tense, distressed, perhaps unhappy, but still functioning — which is exactly why REBT treats it as an evaluative belief rather than an objective limitation (Working4Recovery, n.d.).

What makes frustration intolerance particularly powerful is that it doesn’t argue about whether something is fair or justified. Instead, it automatically concludes: “This feeling, effort, or delay is more than I can handle.” (Harrington, 2005b).

Why “I Can’t Stand This” Escalates Emotions

When discomfort is experienced as unendurable, the emotional system responds with urgency — not necessarily because something is objectively dangerous, but because remaining with it feels impossible (Harrington, 2005b).

Anxiety intensifies because staying anxious feels intolerable, which can create a spiral where anxiety about anxiety amplifies the original anxiety (Harrington, 2005b). Anger escalates because frustration feels like something that must be discharged immediately; research with children shows frustration-intolerant beliefs are associated with more disruptive anger outbursts when desires are thwarted (Trip et al., 2021).

Research also links frustration intolerance with heightened emotional distress and difficulty regulating mood and anger in clinical and non-clinical samples (Filippello et al., 2018; Morillo-Rivero et al., 2020).

Over time, this belief trains the nervous system to treat discomfort itself as something that demands immediate escape rather than tolerance or accommodation.

How Frustration Intolerance Shows Up in Daily Life

Because frustration intolerance centres on endurance, it often becomes visible through behaviour, not just thoughts (Harrington, 2005b; Working4Recovery, n.d.).

Waiting, Delays, and Boredom. Queues, traffic, slow replies, buffering screens — these are small tests of tolerance. When delay is experienced as unbearable, irritation escalates quickly into urgency.

Psychological theory and REBT-informed writing note that interpreting delays as “intolerable” is associated with greater emotional distress during minor waits (Harrington, 2005b; Low frustration tolerance, 2025).

Effort and Sustained Tasks. Studying, focusing, exercising, or learning new skills requires staying with effort and discomfort over time. Frustration intolerance makes this feel impossible, which increases avoidance and procrastination (Harrington, 2005a; Low frustration tolerance, 2025).

Research with students also links frustration intolerance with academic burnout and reduced engagement, which can indirectly harm performance (Ruiz-Ortega & Berrios-Martos, 2025).

Conflict and Emotional Discomfort. In relationships, frustration intolerance can show up as difficulty staying present during tension, where the discomfort itself feels unendurable. 

REBT theory also describes an “entitlement” form of frustration intolerance — a belief that it is unbearable to be overlooked or treated unfairly — which can intensify conflict reactions (Harrington, 2005b).

Across contexts, the pattern is the same: discomfort triggers urgency, and urgency drives escape (Working4Recovery, n.d.).

What Research Shows About Low Frustration Tolerance

Research supports frustration intolerance as a vulnerability factor for emotional distress and maladaptive coping.

In adolescents (12–14 years), stronger low-frustration-tolerance beliefs are associated with higher perceived stress and higher mood-based indicators of depression and anxiety (Mahon et al., 2007).

In adult clinical samples, frustration intolerance beliefs are positively associated with symptoms of depression, anxiety, and anger, with these experiences often reinforcing one another over time (Filippello et al., 2018; Morillo-Rivero et al., 2020).

Broader REBT research also links irrational beliefs (including frustration intolerance content) with psychological distress, with frustration-intolerant themes becoming especially relevant when stressful events occur (Turner, 2016).

Frustration intolerance is also linked to behavioural patterns that increase long-term stress: in student samples, certain frustration intolerance beliefs (particularly discomfort intolerance) predict procrastination severity (Harrington, 2005a).

And in a larger undergraduate sample, frustration intolerance predicted burnout and reduced study engagement, which indirectly relates to lower academic outcomes (Ruiz-Ortega & Berrios-Martos, 2025).

Why Avoiding Discomfort Makes Life Harder

Avoidance often feels like relief. Stepping away from discomfort reduces tension in the moment.

But each escape reinforces the belief that “I really couldn’t have handled that.” Over time, tolerance shrinks rather than expands. Responsibilities pile up, conversations are postponed, and challenges feel increasingly overwhelming.

REBT theory describes this as a short-term relief, long-term cost pattern: frustration intolerance pulls people toward immediate comfort (“short-range hedonism”), but increases long-term consequences and stress (Working4Recovery, n.d.; Low frustration tolerance, 2025).

Harrington (2005a) also links discomfort intolerance beliefs to procrastination — an avoidance pattern that often worsens stress over time.

What begins as self-protection slowly becomes self-restriction.

Building Tolerance Without Pretending It’s Pleasant

Increasing frustration tolerance does not mean liking discomfort, suppressing emotion, or forcing positivity. It means adopting a more accurate belief:

“This is uncomfortable — and I can remain with it.”

When this belief is nurtured with the self, emotional reactions often soften — shifting from extreme distress into more proportionate, manageable negative emotions (Working4Recovery, n.d.).

Research also suggests that strengthening frustration tolerance relates to better persistence and lower burnout in academic contexts (Ruiz-Ortega & Berrios-Martos, 2025).

Paradoxically, when discomfort no longer feels threatening, it often becomes easier to bear (Harrington, 2005b).

How Therapy Helps

Therapy helps people identify and gently question the belief that discomfort is unendurable. Rather than arguing emotions away, REBT-style work targets the belief itself — disputing “I can’t stand it” and replacing it with a more tolerant stance (Harrington, 2005b).

Behaviourally, REBT also emphasises practising tolerance through gradual exposure to uncomfortable situations — “staying with the discomfort” long enough to learn, through experience, that it is survivable (Low frustration tolerance, 2025). Over time, this shifts the lived belief from “I can’t handle it” to “I don’t enjoy it, but I can handle it.”

Therapy does not aim to eliminate frustration from life. It helps reduce the suffering created by believing frustration cannot be endured (Harrington, 2005b).

Discomfort is unavoidable. Effort, delay, and emotional strain are part of living.

What often determines whether these experiences lead to growth or exhaustion is not their presence, but how we interpret our ability to stay with them — and whether we treat discomfort as unbearable or simply unpleasant (Harrington, 2005b).

When “I can’t stand this” becomes “I don’t like this, but I can remain with it,” life can happen. Not because it becomes easier — but because we no longer have to flee from every moment of difficulty .

And if learning to stay with discomfort feels hard to do alone, we’re always just a call away!
