Hey, @galenkp
I meant to comment on a previous post of yours about your health issues and then something came up, and many posts later I see this.
What can I say? Been there, done that. I did it without the sense of confidence you have, so I'm sure you do great someplace else.
I had a student once who, after becoming a teacher became a doctor (some sort of new wave medicine thing). He went as far as affirming that most diseases people have these days were caused by their jobs (from a flu to cancer).
Most of his patients got better after they followed his first instruction: leave your job.
Not sure how much truth there is in that, but it works for most people I know under regular circumstances (a normal country where meritocracy works and the economy does not depend on a paternalistic autocrat).

Wish you the best. First things first, hope your health improves. I'm sure you'll find your niche and do better than before.
Have a great day!
