Ocd or me?

How can I tell the difference between suicidal ocd and suicidal thoughts?

I have constantly been feeling like if I hit one arm, I have to hit the other and if I set something down and it just didn’t look right or feel right I had to do it again or I had to move it to a different spot in my room I’ve had never been a clean freak, which is mainly what I get told is OCD And I don’t know if I should even have this app. I don’t know if I actually have it. I’m constantly worried that I did something in my past that harmed others and that’s why people don’t like me or I’m constantly worried People are constantly watching me and I don’t know if that’s OCD or if I have it so please tell me I will delete this app and never think of it again if I don’t I just really wanna know

I've gotten diagnosed with OCD and I'm in therapy. But I'm worried that I don't have OCD/that I got misdiagnosed. And recently I'm worried that I've just gotten myself into a habit of thinking of dirty minded or just plain old terrible things after I see/hear certain things because I feel like I need to prove I have OCD or else I'm faking(sometimes this goes away). Or that I'm just mimicking symptoms of ocd to cope with real problems I may have and that im just really deep into denial. I don't know...I'm just so tired. I mean, what if I really am what I think I am and this is my brains only way of coping? I don't even really feel anything towards most of the thoughts anymore either I just know they go against my values and I don't want them. I don't know if that's because I'm so mentally exhausted, I just don't care, or that the thoughts are true and I'm comfortable with them.
