I'm trying to figure out if I should be in grad school or not. Birds are my passion, and I always wanted to be some sort of researcher... but...

I would have to take that expensive GRE again since mine has expired already

I have physical weakness too and I'm often too slow doing field work. I've been told I should do lab work, but I don't know how to get my foot in the door.

Mental health issues... I sometimes still get symptoms and even the past research job that I was good at, I developed symptoms and it ruined it.

I'm on SSI, if I'm deemed not able to work... why should I try school? But I don't want to be in this apartment forever.

Suggestions?
