Law can be a really expensive degree to do in the US even though job prospects are well down on what they used to be and most people who 'make it' to big law hate all the obnoxious assholes they're forced to work such long hours with... Medicine, dentistry, law, highest suicide rates. Any concern over mental health would be concern over that.

I'm honestly not sure that I'd find teaching any better. I'd imagine it could be wonderful working in a higher decile (richer) region school... Private... Small class sizes etc... But I don't know how fierce competition is for those sorts of teaching jobs... Struggling with kids who haven't had breakfast and who can't afford books and who can't sit still for 5 minutes even if they had books doesn't sound like much fun to me...

Psychology sounds fun... You might be able to short-cut some kind of graduate diploma to get you the equivalent of a psychology major without needing to do a whole degree since you have one already. Having a bachelors in psychology (or equivalent) isn't really enough... You need to do some kind of graduate program to get to work in the field, properly, but it would be a start...

I think everything is hard to get into these days. And you need to accept that you could get stuck in crappy jobs that you hate on your way to something that hopefully you find to be good...

I've been in school since... Forever. I'm not entirely sure I can do anything outside of it. Mostly... I think I can't. I simply don't get the head space of a lot of people outside academia (especially if I don't have the power to get them to back off such that I can do my thing)....

So... My advice ain't really worth anything...
