whenever I hit my head I always obsess about if I got a concussion

Hello, I was driving last night and i hit a bump in the road like felt like a massive pothole but the road i was driving on (i drive on it almost everyday) and i’ve convinced myself that I hit someone or something. I had my mom drive by there again about 20-30 mins later and there was nothing but she said it looked like a hole was filled by rain water. I drove by later that night and didn’t see it so I’ve convinced myself that if something happened, it was cleared out in that time. Is there anything I can do to help myself feel better.

I was driving when I passed by 2 kids playing with a ball in their front yard, their ball made it to the street, I slowed down and continued my route and looked back to to make sure they’re ok and when I got home I started getting intrusive thoughts that I ran over the kid 😢

but is it OCD if when i get a thought that makes me anxious i have to hit my head a certain number of times to get it out of my head to relive my brain that everything is fine now (doesn’t always help though). or am i just being dramatic?
