I was always on edge for things I forgot or bad things that might happen. Even small day to day things. Along with the anxiousness / fear I felt all the time. Started leaning towards turning into the paranoid prepper type at one point.

Cybersecurity was a natural fit as a career lol.

Once I got on medication, the feeling of fear or anxiety basically vanished. And the depression was more under control. I'm still good at cybersec though. I have had a lot of practice thinking about what can go wrong. I just don't freak out over it anymore.

Later I was diagnosed with ADHD. I don't know if or how that played in. My unscientific pet theory is that constantly screwing up may have heightened my fear of screwing up. But idk how it explains fearing numerous potential adverse scenarios.

Anyway I am more calm and level headed than ever most of the time. I do still anticipate various reasonable outcomes. But I don't freak or go overboard or focus on the scariest thing.
