Is my guilt and overthinking linked to OCD or real intentions?

Does anyone else suffer from ‘Real life events’ OCD? I constantly worry about things I did as a teenager (from ages 15-19) I wasn’t a very nice person and think I was quite a toxic girlfriend in my first relationship. I’m always terrified that people are going to find out and that I’m going to lose my job or something awful. I also think that a lot of people would be so shocked if they knew some of the things that I’d done, and that they would think so much less of me. I feel a constant need to confess or apologise, and wish more than anything that I could erase that whole chapter of my life. Previously in counselling, we looked at ‘black and white thinking’, and I managed to rationalise that everyone makes mistakes and nothing I did was that bad, but I have this horrible feeling that one day this will all catch up with me. Is this just genuine guilt and remorse or is this a symptom of OCD? Thanks in advance.

I hate how my mind is making me doubt of my intentions when i clearly know that I don’t have any desires to act on my thoughts. It makes my intentions feel so uncertain, and sometimes it would even make me feel like if I wanted to act on my thoughts when I actually don’t, because I wouldn’t be doubting if I did. So since I feel my intentions so uncertain I need to come to an answer, and sometimes it is so damn hard to get that answer, which makes me anxious and disturbed. It would also make me think of my past like, how were you okay without having these thoughts? Or makes me think of my future like, will you be okay without these thoughts? So it would make me think that these thoughts are really desires and I won’t be okay unless I act on them. As horrible as it sounds. And I don’t know if someone gets this too but, it would also make me doubt my feelings. When my family tells me cute things like “I love you” and stuff, I would feel so bad, because my thoughts are towards them. So I would say “ily too” but I feel like an hypocrite saying it, or like I don’t mean it at all, so it makes me doubt if I really love them or not. This is all so overwhelming, and I have gone through so many disturbing and crazy thoughts, feelings and situations, that I don’t know if this might be OCD.

Long story short it feels like I might have cheated on a class final project and my ocd is causing intense rumination and mental checking that I did nothing wrong or had no bad intentions. Also feel the urge to get validation from others if what I did was cheating or not and even confess to make the thought cycle stop. My question is how do I discern what I should truly feel guilt for vs what’s ocd just making my life harder by telling me I’m a bad person and done something terrible. How do I just let it go and move on without knowing for sure I did something wrong or confessing?
