Hey, frosty11, and welcome to Psych Central!

Does your school have a counselor or some sort of program like that? By all means I would seek out some aid from there. Just your problems are enough to derail you--both a grandma dying and a mom with breast cancer. No wonder you are having trouble concentrating. You need someone to talk to and to support you.

You would also need to be examined--tested-- to see if you have ADD/ADHD and maybe a counselor could get that in progress if it seems appropriate. If you get a diagnosis, then you might be prescribed some meds.

Same thing with depression, if you get diagnosed with that. You might be sent to a psychiatrist or someone else who can actually prescribe. (Generally, therapists can't prescribe meds.)

Hang in here, dear one. Maybe some of your professors might be understanding, too, so you might speak to them about your woes. They might be willing to cut you a bit of slack. Worth a try, anyway. (I used to be a college professor.) It generally takes a while for meds to start working--up to two weeks. And therapy can take time, too.

I do know students can receive a medical "drop" and come back again to start over with those courses, so check into that if you really feel worried at this point.
