This is a super interesting question, and I don't know the answer.

My personal, completely unsupported opinion is that people now feel more pressure than ever to be perfect, when people are not. It is therefore logical that when people look at themselves and find imperfections, they try to find a 'cause' or a 'reason' that they can blame those imperfections on. I suspect that once you have convinced yourself that your imperfections are caused by something, you have a sort of Baader-Meinhof effect of the mind which causes you to see more and more 'symptoms' and attribute more and more negative things to that 'cause'.

Agree on both the TikTok mental health awareness and gatekeeping points however.
