so the spring semester just started a few weeks ago and i just found out i might have some major health issues. I am really freaking out!

I can not focus on a paper that is due Tuesday and a test that is the same day. I could only focus on math which i finished a few days ago. I dont really have to think when i do math and it like calms me or something so i think that is why i could get it out of the way. Other than that i cant do anything. I could not get out of the bed yesterday and today I can not get off of the couch. Also i have yet to sleep and it is 10am. My depression has hit me the hardest it has in a long time. I am just so defeated and have no idea what to do about school... Help?
