What if vent

I have the thought of what if I lose control and do something out of my control like scream for no reason or yelling in a store or just blurting stuff out that’s not in my control and it causes so much anxiety and causes me to feel weird. I always think I’m on the edge of losing control of myself and it’s exhausting living like this. Any tips?

Two things are happening: I get thoughts that just keep looping. They almost feel like song stuck in my head. Also, I’ll imagine something and I feel my stomach drop. Then as the seconds go by I keep getting fragments of the this thought but with different details. For example, it’s kinda like how a “vision” is portrayed. I’ll get a glimpse of the thought and then it’ll rapidly expand into something worse every few seconds. I don’t know if I’m causing this or if it’s just an automatic thing like any other intrusive thought. It feels unavoidable, idk if this is a compulsion or if it’s just another manifestation of an intrusive thought. Apart from that remembering an intrusive thought triggers the full thought again and then it just keeps looping or expanding. I don’t know how to stop any of this. Help?

Told my close friend about how I think I have harm ocd and showed a video describing her experience with it so I wouldn’t have to share mine. Told him how when I see the number 22 I get paranoid that I’ll harm someone, and he gave me advice to go to a psychiatrist then left me on read after we were having a conversation prior. I’m so scared to open up to people about it and now I don’t think I will again.
