Should I be depressed at 24? ?

I'm 24 bit I feel like a complete loser I only have like one friend I can't remeber when the last time I had sex! I'm not even done with school and I'm so broke. It seems like everyone around mr has it all together I need help sometimes I just want to break down and cry. Take facebook for example I have like 200 friends the people I went to school with have like 1200 plus lol I was always liked I don't understand. I love to party but yet I'm never invited out I have no1 to even go out with. I really feel like there is some block on me or something I've gotten to the point now that even my faith in god is not what it use to be . I often times drink a entire bottle of wine n take sleeping pills with hopes not to wake up the next day but I always do and it makes me mad. I know. something is wrong feeling this way has to be depression the only reason I'm in school is b/c it seems that's the only way to leave this city I'm in where it seems like a great looking nice young blk guy is the devil and b/c I'll have a good paying job. I use to want to be an actor so bad more than anything I still daydream about it cuz when growing up that's the only thing I seen myself being now there's a painful void within me cuz I never had a chance to fulfill it. Please someone offer me some words to go by don't be rude i'm at a very hard time in my life right now
