Does anyone notice that when their OCD is worse that it triggers depression?

Sometimes I notice my intrusive thoughts cause me to spiral and sometimes not. I've been practicing ERP for quite a while so it's a bit easier for me to not spiral. But I wonder why that happens. Does anyone else have it? Also I'm on medication idk if that plays a role.

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.
