First: breathe! Second, try to talk to the person responsible for your campus and ask if it's possible to stay in that room (I see no sense in sending you home for 4 days...). Third, talk to your parents (if you haven't yet) and ask their opinion... They may not be able to help you financially, but they may give you some nudge into a solution... I hope everything works out, and wish I could help more...
Do you have anyone to talk to to help with the stress? I'd try going to free events at your university. Some places serve free food and have a good community to help support those going through a stressful time.
