I'm very sad...my dreams for Italy smashed...?

I feel depressed. I was supposed to go on a study abroad trip this summer to Italy with my school, but I also need an apartment to live in with my room-mate because our school is kicking everyone out of the dorms. Well, my mom won't cosign any loans for me so I have to do things by myself. That means that this wonderful trip with these wonderful people won't be happening, I think I'm going to have to use the study abroad money for the apartment and its making me feel the worst I've ever felt. I'm going to have to tell my teacher and the kids in my group...I'm just really sad right now. I'm going to try to save money to go next year maybe even use financial aid from my school and live there for a semester instead of just a month. I hope it works out. I just need to talk to someone because this all happened so fast...can anyone help me with suggestions about visiting your beautiful Italy? Also, what time of the year do you recommend going?

I just can't believe this happened!

I'm just worried that I'll never be able to go since I have to pay for an apartment and the costs for the program. It's pretty much impossible to get loans for these things unless you have a cosigner; which no will do that for me. I feel like I'll never be able to do anything great like this...I had such big expectations for this trip and I feel like someone just stabbed my heart out.
