I have to gag myself with my toothbrush 8 times every morning before brushing my teeth or I feel like something bad will happen. Any one else do things like this?

For the past couple of months, I’ve had a really big fear of like my hand basically going down there or objects going down there and like being contaminated. This basically leads me to be scared of being on my own and doing things without people near (because if I do everything in front of someone they would tell me if I did something), also tucking my shirt. This started last October too and I remember crying for like hours everyday. Now I’m better but I do compulsions like tucking my shirt in a specific way so I know my hand couldn’t reach there. I’m scared to even get ready for the day, brush my teeth, etc with my shirt untucked because I’m scared those objects will be contaminated or I’ll do something to contaminate them. I’ve been trying to stop this compulsion of tucking my shirt in for a while but I’m not really going anywhere.

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?

does anyone else just count for no reason? like their steps or how many times they move. just a few minutes ago i was scratching an itch on my leg and and caught myself counting how many times i scratched😂😂 and recently i’ve just been counting to ten randomly just in my head it’s so random or if i catch myself tapping on something i tap ten times. i got rid of it kind of like i used to do things 37 times or 3 times or 7 times 😂 3 and 7 or just the number 37 was the number for about like 10 months it was BAD. and i also have to turn on a light switch the right way but i don’t know what the right way is tho and it never feels right so i have to literally stop myself and walk away but i usually end up coming back cs ill think about like an hour from then and how ill have this weight on me because i didn’t turn the light switch the right way or the right amount of times but then i literally usually always forget about it so like idk am i weird orrrr does anyone else do thissss 😬😬😬😬
