OCD tendencies coming back due to programming?

[N8RzwA7f]

I used to have severe (as in leading to suicidal thoughts OCD ) for 20 years. Since a few years it's simmered down. But now with all my programming, I notice I nitpick about EVERY LITTLE TINY DETAIL that I could have possibly messed up and go over my program in my head over & over & over driving myself (& those around me) absolutely batty.

Now I finished my first app . And instead of feeling happy joy joy thoughts, I just am thinking repeatedly I made some mistake somewhere that will show up (it debugged fine) but I can't find any peace or reassurance at all :(

I'm surely not the only one with this going on ? Anything that helps ?

thanks :)
