I feel like my thoughts attach on to any and everything smh

I been dealing with intrusive to the point it feels like I think them idk what to do I feel like a monster.

Alot is on my mind u feel like I’m going to lose my mind , not really a lot but if I think too hard I think I’m gonna lose my mind , I was trying to slp n I think I’m gonna lose my mind , I’ve always been having thoughts about going crazy it never really changed , I have other thoughts and triggers but they always somehow lead Bk to me thinking I’m going to lose my mind , guys I’m so tired , do I even have ocd

I know the solution is to always say “yeah that could be true, but I am choosing to live my life anyway.” However, I feel like my biggest issue is my brain always assuming that it is immediately true when I do that. Like if I say “maybe I’m attracted to teenagers, it’s possible,” then my brain INSTANTLY starts rationalizing that thought and defending it and being like “oh okay so you think this now and it makes sense because xyz, and now that’s who you are and your real desire is now and always will be teenagers.” I feel really alone in this area of feeling like my brain “accepting the thoughts” means my brain immediately accepts them as true. I obviously don’t want to think they’re true but I feel so stuck now.
