how to stop

I need help stopping my compulsive thoughts and worrying

I'm new and I'm really trying to control thoughts of replaying interactions I've had or things I think might happen with the people around me. This is something constant, and it causes me to repeat actions. Then I lose track of time and often end up being late. It has always affected my sleep and becomes a part of my dreams, which are also always vivid. It's always been hard for me to get up. I just constantly keep replaying different outcomes of things that it haven't happened yet going over every possible outcome with no correct answer. I'm scared of what I might say and do when at work because it's been getting worse lately. I've been terrified of socializing, because I feel like I'm going to lose it every time I speak to someone. I work directly with people doing their hair. I don't want my clients or co-workers to catch me in the act of one of my rituals or it to effect the job that I'm doing. It just makes me angry that I haven't been able to control these thoughts and it makes the rituals worse. Then I feel embarrassed after I finally stop repeating whatever it is, I'm doing. I feel like I can't trust anyone, and I’m terrified but I know it's not real. I can't afford to lose it/show it.

does anyone has any tips how to stop the "what if cycle"?? i have very disturbing what if thoughts on daily basis and they're rlly scary always. i know they're not real but sometimes they feel so real and possible to happen and i hate this
