Any advice on stopping/reducing the severity of compulsions? Getting to a point where my nightly routines are almost impossible as they are so particular

Usually my compulsions are always motivated by fear. I feel like a child when I have compulsions. Like for example, my brain convinces me that someone is in my house and I need to open every cabinet and all the shower curtains, and do tons of other crazy things like march instead of walking so that if someone where to shoot at my legs they'd have less of a chance of hitting me. How do I stop it? I am just going about my day and I can see in my head, myself getting attacked or something and so my only option to calm myself down is to do a bunch of random actions that will keep me "safe". Does anyone else experience this? Or convince themselves that they are under Milo Murphys law? That anything bad that can happen to them will, so they need to never do anything that could result in anything bad, and avoid everything? And how do you convince yourself you're not in danger?

I’ve been stuck in this cycle for the last month or two and am not sure how to get out of it. Basically, I will work on ignoring the thoughts and not responding or engaging plus limiting/completely eliminating compulsions. After a week or two of constant work, the amount of intrusive thoughts in a day goes down. The anxiety each thought causes also goes down with some, but not all, thoughts passing without notice like they would for a normal person. The thoughts that do stick cause anxiety and make me want to ruminate or do other compulsions but I make sure to limit them. After a bit, I’m in a pretty good head space. This is usually when it goes down hill. I’ll start to question if I even have ocd because some of the thoughts (once again not all) pass without notice. The difficulty resisting compulsions goes down and so does the anxiety, only increasing the questioning. I spend a while questioning if I’ve ever had ocd in the first place and then something sets me off or the questioning itself becomes a trigger and I get stuck back into the same ocd cycle with constant rumination, anxiety, and other compulsions. This lasts for a week or two before I know I need to stop and try and work hard to get back to ignoring the thoughts. And the cycle just restarts over and over again. Does anyone have any tips to stop this from happening? It’s really harming my recovery as every few weeks I dive back into the same negative place I was.

This is a repost, only because the last post had no responses lol. Please if you have any advice share. I’ve been trying hard to sit with the feeling of anxiety. Actually that’s the problem, recently I’ve been trying to sit with the thought (and I’m able to for a few hours or until the next morning) and then my anxiety comes back so strong and it’s like I need to clean everything off. I see images of gross laundry getting on everything or my hand and then I need to clean everything off to un contaminate it. Sometimes the thought happens later at night so I just sleep through and the next morning I will wake up with intense anxiety about contamination. That happened yesterday and I had to clean everything off and since then I’ve been traumatized so I’ve been doing compulsions like avoiding the bathroom and being around people so I know I couldn’t have done anything wrong. Actually recently my biggest compulsion has been recording every time I get up to go eat, etc so that I know I couldn’t have done anything. Any advice or help???
