Do you get random anxieties but don't know what you are stressing over ?

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.

I have the thought of what if I lose control and do something out of my control like scream for no reason or yelling in a store or just blurting stuff out that’s not in my control and it causes so much anxiety and causes me to feel weird. I always think I’m on the edge of losing control of myself and it’s exhausting living like this. Any tips?

Does anyone else ever feel like this? When you're having a good day without a lot of fear after having multiple days of fear, you start worrying that your good day will be ruined by fear again. It's like anticipatory fear. Anyone else get this? I hate it but I don't know how to make it stop
