sometimes the compulsion is in my head I often think of certain colors or words to make my anxiety go away

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?

Hey so my OCD makes me hate specific numbers and words, like I can’t say some words in case that specific word comes true and something bad happens. I then go and keep saying to myself everything is amazing,everything is amazing and it just tires me out.

but is it OCD if when i get a thought that makes me anxious i have to hit my head a certain number of times to get it out of my head to relive my brain that everything is fine now (doesn’t always help though). or am i just being dramatic?
