I am constantly working my ass off to try and do well and it seems like whenever things become super important or super stressful I mentally shut down. It is severely impacting my ability to do school and in the last two weeks I have completely fucked up my grades (when I was doing rather well) bc I'm in an awful mixed episode. Please help me, any advice is appreciated, because I've already had to drop out of college once and I am on my second try now.
