OCD and being around people

When i see something, get reminded of something or talk to someone that triggers my train of thoughts, i feel a sudden racing spike in my heart, a knot in my stomach, kind of like that nervous butterfly feeling you get when you’re on a rollercoaster thats about to go downhill, or when you get jump-scared. My hands start to sweat and i just want to remove myself from the situation asap, wishing i felt the way i did about 2 minutes ago when i was doing just fine and wasn’t overthinking for once. The OCD goes wild in my head, instant overanalysis, sending me down into a spiral, making me want to dig a hole and hide in there until i somehow manage to persuade myself im not a bad person before I can go about with my day with ease again.

I have never dated anyone bc of the fear that ocd would flare up too much and cause problems but this time i have taken a leap of faith and thought to myself that whatever ocd is gonna throw my way I will deal with it cause that's what I should be doing cause I can't not do anything in my life. What are your tips to when my ocd flares up due to me dating

I don't know if anyone else has a similar problem, but I think one of my themes is worrying how others might perceived me. For context, I used to be very shy and sometimes don't have good control over facial expressions. This leads a lot of people to believe me being hostile to them, even though I don't mean to be. Now, I moved a different city and am meeting a lot of new people. And this makes me really worried of leaving bad (first) impressions.
