I am really afraid I am going to do bad things so people will treat me more like an adult 😭 I keep getting all these intrusive thoughts about it and I don't know what to do bc they feel so real

I am so scared of everything .Of my thoughts.If I am a good person.Years ago I didnt help a kid who was in danger.Since then I started to have terrible thoughts :( i am so terrified.I still have these thoughts and I am scared it means something about me .I really dont want to hurt anyone and I want to help that kid now but idk how I can now.Also I am scared I betray everyone.I still have terrible thoughts and when I am with someone I care is worse...idk why.For example I started to talk with a collegue and he is really nice to me.I told him some things abt me( not the intrusive thoughts) and he was supportive.I have no idea if I will tell anyone abt my thoughts..and bcs of that I feel like I lie to them and betray them.I really want to enjoy my life and be happy and support people( especially because I didnt help that kid then).I want to live up to my morals now but I feel like I lie and manipulate people bcs I am a monster.Is this normal? To feel this way? What can I do? What if I am my worst fear and just cant accept it?!

I have no idea anymore. I guess this all started with me worrying about whether I was gay, then whether I was a P, then worried about being just attracted to teenagers. After that I started freaking out about not feeling “grown up” enough. Like “I’m an adult wtf is wrong with me for seeing someone who is probably younger and thinking they’re physically attractive. Then I started overthinking not finding older adults (like 30 or 40) very attractive. Like ofc I’m probably not gonna find them attractive, they’re not anywhere close my age. Maybe the desires are half real. Maybe as a 21 yr old young adult I do find older teenagers (16+) somewhat physically attractive. I still think it’d be weird to date one. Maybe that’s the normal reaction I’m supposed to have. If not, please let me know. I just don’t wanna do anything illegal one day and I’m super scared I will. I can’t tell if the fear is my just being afraid of the law though, in which case I might actually just be a bad person. I hate that my brain is just rationalizing thoughts now. I feel like I can’t do the ERP thing of “just accept that the thoughts are there but don’t engage.” Like what? How can I just think a thought that might be so integral to my identity and just ignore it? If it’s all true and I don’t like people my age anymore then I have to know and plan around that, that could change my entire life. I’m rambling, my b.

How do you guys handle uncertainty? I keep having so many what if thoughts and I feel so bad. The worst ones are what if I act on my intrusive thoughts or actually want them and I can’t tell if they’re me or not. It just feels so real and at this point I don’t even know if they’re intrusive thoughts anymore. I just want to not be a bad person and not feel like this anymore.
