I used to work as a programmer, and I made a lot of mistakes due to confusion. I eventually left on a medical leave of absence.

I have OCD so perhaps I see it everywhere, but the inability to stop obsessing about details combined with anxiety may be a form of OCD. Also "perfectionism" might be involved here. My father was a mechanical engineer, now retired, and he's practically crippled by OCD and perfectionism now. He was a very slow worker when he was working.

I don't mean to pathologize your condition... you are a full human being who is deserving of care and understanding your situation from every angle, including the meaning of these events as seen by your human personality. However, to say it's OCD means that perhaps either therapy or medication for OCD could help.
