ADHD or mental compulsion?

so, i’ve been thinking i have ocd, but my dad said that adhd is really bad in my family, so could it be adhd instead of ocd?

I am diagnosed with OCD, ADHD, and mild depression. But my OCD symptoms are so prominent in my daily life where it feels debilitating. It comes in waves, there will be months with very minor symptoms and other times where it comes in random hitting me like a truck making me rethink life. I grew up having intrusive thoughts of all types, and a lot of them sent me over the edge because I couldn’t understand why things of such sort would cross my mind, things that I’m sure to this day that I’m incapable of or would never want to actually do. Yet I find myself in a constant cycle of trying to dig deep in the past and trying to figure out if I ever acted on any of the intrusive thoughts I can remember, yet ofc have no recollection of acting on them because they most likely didn’t happen. However, not having concrete proof of these things makes me not want to see another day sometimes. It is so hard to move into daily basis like this. I’m also in a happy healthy relationship and sometimes I get these thoughts of “what if I’ve done something awful during the relationship (for example, cheat, dishonesty, etc.) and can’t remember?” I know I would never do anything intentionally to harm my relationship and I think that maybe the idea of not having my partner sends me down a rabbit hole to think all these things. This mental fight is getting harder and harder. It feels unbearable. Does anyone have some fruit for thought, relate, or have any tips?

Guys, I would like help with maladaptive daydreaming and impulsivity. What would both be in OCD? I've always had daydreams. But it was something I did because I liked creating stories. But recently I've noticed that sometimes when I'm stressed, if I think about a situation, it feels like I'm going to imagine it or want to imagine it. When I say don't do it, it feels like it's basically going to happen. I talked here the other day about what if I try to create a compulsion to get out of my subject? Yesterday I was so anxious and I did this counting thing. Then it came to my mind, "put something like, if you don't do this, someone will suffer harm." And I don't want that. And I don't even want to create this compulsion because I would know that it would be worse because I would never risk it. But the thing is, even though I had a clear idea, it seemed like I was going to do it. I just wouldn't let it happen. Is that daydreaming? Is that impulsiveness? This has happened to my OCD theme before. But I had the feeling that I wasn't taking things seriously. That I was being childish. But I don't do it on purpose, it seems like I can't get out of the habit. Thanks for the help!
