Constant anxiety

So I’m starting therapy this week but I’ve been trying to use ERP myself, my main compulsion is rumination which I wasn’t even aware was a compulsion. I’m trying to do ERP but when I focus on observing the thought it goes, I dunno if I’m focusing too much on actually how to follow ERP or is this normal? I feel like I might be subconsciously blocking thoughts because I know how bad it is when I go down the rabbit hole, but then I also worry that the anxiety goes too quickly and that I’m finding it too easy to ignore the thought?

So, I think I’ve had enough time with out ocd symptoms to know that my intrusive thoughts are just that, intrusive thoughts. However, I’m having a spike right now and again it feels so real. I have tried erp before and I would ruminate the whole time after the exposure and I would try to stop it but rumination for me is so automatic. I don’t event know I’m doing it sometimes. I would want to start erp again but how can I stop rumination? I know if I don’t stop it, then I’m not doing the prevention part which would then not benefit me at all . Anyone has successfully stopped ruminating after being triggered?

So I got diagnosed with OCD this past summer. Since then I've been in ERP therapy for my OCD. I'm 24 and it took a long time to figure out that what I had was OCD because a lot of my compulsions are internal. I struggle a lot with rumination, my brain just chewing on the problem to find a definitive answer. My therapist told me to focus on the feelings in my body, to try and be present in my body and not just stuck in my head. But it's really hard because I don't realize I'm ruminating until I've already started and it can be hard to drag myself away from it. I usually just start ruminating about something else related. My question is, does anyone have any tips and tricks to stop ruminating? I read the article by Dr. Michael Greenberg about stopping rumination but it just seemed like his advice was "Just don't ruminate" and it was very stressful.
