Sad/depressed feeling!? BUT WHY!? Anyone relate?

These past few days I was fine. Minimal intrusive thoughts ,no anxiety etc(to add I'm on medication so maybe it's starting to work although it barely is 2 weeks) and today I got a sudden wave of anxiety and it started latching on some thoughts like" what if I'm in denial and I wanna break up with my bf? And what if erp doesn't work for me because I actually wanna break up with my bf?" But they didn't really stay long usually those thoughts would make me spiral for days or so, now they lasted for some hours. And now I'm trying to trigger myself into being anxious again because if I don't it means I don't have ocd and if I don't have ocd it means I don't love my bf and if I don't love my bf it means I have to break up. Idk if it makes sense but the lack of anxiety makes me wonder if I actually have ocd or not.

Can OCD mimic depression? With this theme I’m always wondering if I have OCD or depression. It first started out as harm OCD and now this. Today I told myself if I did have depression then it’s treatable and I would work on it. Then I started to feel depressed and emotional and like had an urge to google the difference. When I did this I just broke down because I felt like I related to them, it made me worse. However when I look up OCD symptoms it makes me feel better. So now I’m unsure. Almost like OCD wants me to believe it’s depression

Does anyone else ever feel like they don’t feel “bad enough” to have OCD, or that they don’t feel “the right way” for it? Or like they’re just saying they have OCD as an excuse? Because i was so much better for like 3 weeks now and now im on my period and i started doubting again. So because of that im scared that i was feeling to good and that my fear is actually true.
