How do you stop caring what others think of you?

So maybe the title wasn't the best to to put it but when you guys start having obsessive thoughts how do you stop them before it turns into compulsions and anxiety?

Today I've let myself go down a huge rabbit hole regarding this phrase and it's stressing me out. Sometimes, yes, it is that deep. But other times, it really isn't. I keep finding myself torn between these two ideals. I've been seeing all these videos regarding the rise of anti-intellectualism and the anti-woke mob, all that. These videos make me extremely worried about cancel culture and moral guilt, and they had me rethinking every morally wrong, gross, questionable thing or thought I ever had. I saw many comments saying that yes everything is that deep and it feels like my mind is on constant security and asking myself "what would the internet think about the things I've thought of or may have done?" On one hand, I feel like if I say "it's not that deep", I feel like a hypocrite or a bad person or an idiot. But on the other hand if I say "it is that deep", my OCD begins to spiral and analyze everything about myself. It's not healthy to overanalyze everything but it's also not healthy to ignore bad things. It's very stressful Does anyone relate to this?

I’ve been thinking a lot about how OCD changes the way we see ourselves, but I recently realized that I am not my thoughts. Just because a thought pops up doesn’t mean it’s true or that it defines me. I’ve started learning how to see OCD for what it is—just a disorder trying to trick me—and I’ve become stronger in dealing with it. Has anyone else here had a similar realization? How do you handle these thoughts when they show up?
