Adjusting to single life

I was in a relationship for over two years, and it ended badly, last november. He made up my whole life, i planned around our time together, every minute it seemed we were together which seemed like a good thing at the time. Now that Im single however, it seems as if i dont know how to be single. In other words, I rebounded with a very good friend of mine very badly, and at the same time, i've been doing a lot of drinking and (safe)messing around with other guys. I've come to realize that this is not what i need, but i dont know why i do it. It hurts so much, and i dont know what to do with myself anymore. I think that the drinking is becoming a problem, which i informed my therapist about already, but still...its not helped anything. I went to a party last night, saying i was going to have one drink, and i had 5, which for someone of my size (im very petite) is a lot. I dont know what to do with myself, ive stepped out of my rebound relationship, and i know that i shouldnt be messing around with anyone at this point. Its hard for me to even hang out with friends because most of them are guys who all like me, more than a friend. So i feel as though i've sort of become a loner. I feel like i did way back in the day, when i literally had no friends. My depression is rampant, and all i feel like doing is sitting at home and drinking by myself, which for a 20 year old, isnt very healthy. Its not healthy for anyone, but as a college student, you socialize a lot, but now i feel like i have no one left to socialize with. I feel completely alone, and I dont know how to handle all of this. Its bombarding and completely overwhelming. I guess all i really need are some words of courage advice or comfort, because any kind words right now would be helpful. I dont even know if i have an actual alcohol problem, but im pretty sure i do, i dont know what to do about it either. So if anyone has some steps to deal with that problem...then i would appreciate it.
