 Throwaway because this is a subject I'm mega anxious about!!!

Basically, the title: Does anyone else have severe anxiety about being "cancelled" online/losing their livelihood etc. because of stupid things they did as a teen? I'm just petrified that people will find out about bad stuff from my past, they'll tell my employer, I'll lose my job and never find one again, my life will be ruined, that kind of thing. When the thoughts hit they just cycle and cycle around my brain and I find it so hard to function because what's the point in doing anything if my life will eventually be ruined for things I regret doing? I have to go through all of these compulsive behaviors like Googling my name to see if anything bad comes up and seeking reassurance from loved ones just to feel slightly better, and even then the fear still remains a bit.

Am I totally alone in feeling this way, or have other people experienced it to? If so, how did you manage to overcome it?
