Beating Myself Up Over Mistakes

Today I got a traffic ticket, my first moving violation in my 7 years of driving thus far. I didn't come to a complete stop. Something silly and careless but no one was hurt or anything. I had a perfect driving record previously. I am in a thought loop/spiral beating myself up over it, even though I know what's done is done and everything is fine now. Wondering if anyone has any tips or tricks to interrupt these nagging thought patterns of beating myself up over mistakes? I tend to do this and we all know how hard OCD can be to overpower. I also messaged my therapist and am waiting on a reply, but she is out of office today. Thank you!
