OCD Intrusive thoughts?

I was doing my eyebrows yesterday using a NEW razor blade and then decided to get rid of the peach fuzz around my face (big mistake!). I ended up with multiple tiny cuts around my chin area, washed my face with cold water and went about my day. However I started getting panicky during the night and kept getting these recurrent thoughts that I may have caught something from that razor (hiv to be specific) Now I know very well that is not possible but I can’t seem to shake it off and couldn’t sleep and kept having so many scenarios playing in my head. This is not the first time this happens... I’m really considering getting help at this point it’s so exhausting 😭

I don’t know how to go about it. Will I be taken seriously?
