What is bane of my existence?

The "bane of my existence" is an idiomatic expression, not a proper noun or a defined subject with specific, universally agreed-upon information. It refers to something or someone that causes persistent and significant trouble, annoyance, frustration, or unhappiness in a person's life. The specific "bane" varies wildly from individual to individual.

It's essentially a hyperbolic way of describing a constant source of aggravation. For instance, one person's <a href="https://www.wikiwhat.page/kavramlar/noisy%20neighbors">noisy neighbors</a> might be the "bane of their existence," while another person's <a href="https://www.wikiwhat.page/kavramlar/tax%20season">tax season</a> could hold that unfortunate title. Other examples might be <a href="https://www.wikiwhat.page/kavramlar/procrastination">procrastination</a>, a difficult <a href="https://www.wikiwhat.page/kavramlar/boss">boss</a>, or even a recurring <a href="https://www.wikiwhat.page/kavramlar/technical%20problem">technical problem</a>.

The term implies a feeling of helplessness or being perpetually plagued by something, even if the issue seems trivial to others. The intensity of the phrase suggests it's more than just a minor inconvenience; it's something that actively diminishes one's quality of life in some way.
