Rejection lead to depression Help!

Sophia
I was a nobody in high school and every guys I liked rejected me so I pledged to myself to change once I go to college. First month of college I made lots of friends and talked to new people, it was fun at first but now every guys I met turned out to be such disappointments.The first guy I talked to was such a player he slept with any girl that walked pass without me knowing. The second guy I talked to got drunk and cheated on me at the party after that he never talk to me again and everyone after that turned out to be just like the rest and by everyone I mean like 5-8 guys!. It stressed me out so much that I would go home and just cried and cried, I turned out to be an unproductive person until one day I met a guy and I though he would be just like the rest but I talked to him anyway cuz I though he might just be a good rebound but he got really serious and was extremely nice, I met his family and friends they all love me. We all hung out all the time. But out of no way he got another girl hiding from me and when I found out he never talk to me again. I was inlove with him more than any guy I ever been with so I'm extremely hurt. Now instead of making me feel better he made me feel even worst than ever. I cannot go a day without waking up crying and the wrost part is since then I don't feel like talking to anyone. Any guy that came in I just feel like they just another joke. I don't think I believe in love anymore. And I know it seem like I talked to a lot of people but trust me I wouldn't if one would at least be true to me I kept telling myself to move on but it turned out to be even worst everytime.
