Decide Whether to Stay In or Leave a Situation You Have Been Tolerating

You have been tolerating it for months and telling yourself you will deal with it and not dealing with it and the not-deciding has become its own ongoing cost. This works through what you are actually tolerating, whether the thing is fixable or structural, whether you have genuinely tried to change it, what leaving and staying realistically cost, and the question you keep not asking yourself because the answer might be inconvenient.

I have been tolerating a situation for longer than I should have and I cannot work out whether to stay and try to improve it or leave. Help me think it through by: clarifying what specifically I am tolerating and why I have not acted yet, distinguishing between what is fixable and what is structural, assessing whether I have taken the actions that would give leaving legitimacy (tried to change it), estimating the realistic cost of both options, and identifying the one question I have been avoiding that would make the answer clearer. The situation I have been tolerating is [describe it: what it is, how long it has been going on, and what you have tried so far].
