125K per year!?

That's over 4 times my salary and I have degrees in chemistry and chemical engineering.
What is sounds like to me is you're brilliant. In your past, when you had to step into public school you got bored quickly. It may not have felt that way, but is part of the reason you just didn't care. It was too easy.
Now, it sounds like you're falling into that same funk. You're too smart for what you're doing so it's pulling you down.
At least, that's what it sounds like to me. I don't think getting your degree or anything will make much difference for a while unless you're talking PhD or something. I would suggest taking this to a therapist and talking through it. Find out the real root of your issues.
But trust me, that degree doesn't mean anything ... obviously.
