I feel you. First semester my grades dropped so low that my school asked me not to come back but I explained to them that I was in and out of the hospital so they gave me another chance.
I made a deal with my mom that if I got above a 3.0 this semester she would pay for my circus aerialist training and its helped a lot. Definitely try to set goals and work towards it. And once you get your grades up, transfer the hell out of there. You don't want to be anywhere where you don't have the right energy to succeed.
