The question why me selects one outcome from a world in which somebody had to experience an outcome.

Asking why me presumes that being singled out needs explanation, when in a world of this size, some particular person was always going to be the one. That is not a comfort exactly, and it is not an accusation either; it just means the question may not have the kind of answer it is reaching for. Being chosen and being included in a large number can feel identical from inside.

If you are in the middle of something hard, you do not have to solve this. Nothing about your situation is a verdict on you or a debt you incurred. When the question comes, you might try setting it beside a different one, what would help today, and let that be the one you answer.
