It seems that sometimes people want to blame every problem in the world on themselves so badly, that they invent their own problems (or "problems") so they have something to blame and criticize themselves over.

      And by "problems", I mean imaginary problems or finding ways to criticize subjective things that do that are actually fine. Often they might criticize a decision they made, excessively emphasize an imperfection about it, or unnecessarily attribute something negative towards the decision, their motives, or their character at the time that they made a decision. And they might really, and naturally stretch in their minds for a reason for why they should regret , even if that decision was actually fine, and even made with a pretty good level of confidence at the time; like a bridge to criticizing who they are as the person behind it, to highlight their perceived deficiencies to put themsleves down.

      But actually, a lot of these times these people come up with every reason under the sun and amplify every imperfection to criticize what they did there, chances are matter what other good or currently presented as better option they picked, they still would have found a way to be unhappy with themsleves over it. 

      And this is sad, because even if you can point this out and get to them, you will likely find them caught between releif and guilt, because you are talking to a person who has somehow come to beleive that under no circumstances should they not feel bad about themselves.
