Is thinking about the same thing continuously for a year ocd

I was diagnosed with OCD around the age of 6, subtype- contamination primarily. It calmed down as I got older and I assumed it had gone away, but also didn’t realize it can show up in other ways, and it still had been effecting me which I know now. I’m not 31 and I’ve been in therapy for a year and it’s helped a lot, although I sometimes get thoughts that what if some of the stuff I’m dealing with isn’t ocd and I’m exaggerating. I feel like thoughts will feel sticky and I’ll do certain compulsions but then the thought eventually vanishes if I do it a few times which makes me think maybe it’s not OCD since other people/friends I know would probably do the exact same thing. Not sure if I’m making sense, but I guess my question is if that thought comes up with anyone else? Just being unsure if something you’re doing actually is ocd or not.

I’ve been triggered so bad this week I’ve had bad anxiety and feel depression coming on. Last night I had a thought oh let’s plan it and I immediately thought why would I think that and started crying bad. I’ve had these thoughts for 7 months I really don’t know why I’m having these thoughts, if I knew I would work on it. Like people say has something happened in your life for you to have these thoughts and nothing has happened, it all started off from what if thoughts , like “what if I’m a psycho” because I saw this fb post saying introverts are more likely to become psychopaths and it all spiralled from there I started getting thoughts about harm towards others and myself. What do you think guys should I treat it like ocd or do you think there’s something seriously wrong with me.

How long do you guys have to sit with a thought for it to go away? I have sat with thoughts for days and days before and the anxiety was crippling to where I couldn’t eat or sleep. Until I asked. And especially something I’ve already asked about before that upsets my husband but my brain was like did I hear him right? Yada yada. That’s about where I’m at right now. I feel so sick from anxiety
