Does anybody else keeps repeating words mentally? I get thoughts about diseases it sucks

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.

My ocd them has gotten worse and I’m trying my hardest to not look for reassurance. Why does my mind play these tricks on me that I’m saying my thoughts out loud????? I’m trying my hardest to ignore it but it’s making me depressed. When I’m ignoring it my brain will go to “everybody will talk about you” “you said something bad” “you said it out loud and when you’ll live a terrible life”. I don’t know what to do anymore

Anyone else have repeated thoughts that play that are negative. Basically a back and forth of you telling yourself you don't want X to happen but having a thought that slips saying you do. Like being stressed out one day and saying "man I wish I were dead". But instead of letting it roll through your mind and thinking nothing of it, you obsess if you actually want that outcome for yourself and you are now scared you'd fatally harm yourself whenever you feel anxious or stressed even though you know you wouldn't. So now I repeatedly get I wanna die stuck in my head and I feel the compulsive need to say no I don't to combat the thoughts and it happens throughout the day and even when I wake up.
