I'm really depressed at the new university that's causing me to get bad grades? help?

I met some girls in a church ministry which I stopped going because i'm not really that religion and I had a bad situation going on with some girl I me there. A lot of people if not most already know eachother from before. I was in an a college ministry. I tried a few organizations at college which I didn't like. I just transferred last semester and i'm not liking it. It's hard to find time to talk to people in cles and I actually dropped my cles. I got one cl and that cl is super quite and there's no group activities so it's hard to get to know anyone. The cl is pretty straight forward. I DON'T want to go to a club to meet some girls or the bar.........I don't want to do online dating!!!! I haven't tried other organizations bec. i'm not really interested in it and plus I been discouraged bec. I didn't enjoy the few organizations I tried....I don't have to grades to join a frat!! my grades are real low due to depression.....I met some girl in my cl LAST SEMESTER(she had a bf) and she all of a sudden stopped talking 2 me...I didn't compliment her so I definitely didn't show I was interested in her in anyway besides a friend!!!!
