Please help me......

Im really sorry hes so sick! That sucks! But i think you should go see him. Bring him flowers or somthing. Ive been in the hospital alot and flowers actually help make you feel better. Like sombody actually cares about you. Other than that just tell him how you feel. If hes a good guy than he should do somthing about it. IDK how old you are but if your old enough...or able to...Go see him. Trust me that means alot when your alone in the hospital. Hope this helps. I agree with FireByrd15, this is kinda vague. If you need more help just message me and ill try my best :) Hope it gets better sweetie!

Try to asses one problem at a time, Visit the guy in the hospital, talk to him if you can.
Once this is out of the way then try to find out why your friend is mad at you, there may not be a real problem, friends get mad sometimes and the best thing to do is give them some time and talk to them later. (Usually a few days works, maybe shorter.)
