Can’t do compulsions correctly

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 don’t want to do my compulsions. I feel like if I don’t somebody will get hurt, sick or die. It’s a very scary thought to feel like if I don’t do my compulsions it will be my fault even though it isn’t & nor will it happen. I know it’s magical thinking & my thoughts are not true nor will they come true. it’s just im so tired of doing these compulsions. im so tired of feeling like I can stop something bad happening if I don’t step on this or touch this 4 times. it even got me believing that if I do something I want to do & love, something bad will happen. I just want to be able to live & feel like I use to. I hate ocd. how can I calm this down so I can be able to navigate in my own life?

How?
