Im having some serious problems with friends and at home... PLEASE HELP?

I've been having this huge problem this past year. I'm acting very Antisocial, especially around girls, but also a lot of my friends. Im 15. Last year and whatnot I was talking to all my friends, many of which were girls. But lately like I just don't talk to so many of them. I still have a lot guy friends, and I hang out and talk to them a lot, but I'm losing my touch with the girls. I think my Antisocialness is related to my parents like fighting a lot and all that stuff. I haven't told anyone about it but they might be getting a divorce, I don't have any brothers or sisters so its like being alone in a storm. A lot of my friends think I'm really funny, and I tend to make a lot of sexual jokes. This past year I've become extremely close with a lot of my guy friends but drifted from all these girls. It's bad because I'm losing practice talking to girls, and I'm losing a lot of friends. Everyones changing but I feel like I'm just boring and stupid and too-young for my grade. I want to talk to all my girl friends again, and I want to have the social qualities I used to have. I want to be able to deal with my parents problems and not like it subconsciously get in the way of my socialization. Facebook is a huge thing. I used to talk to all these girls all the time on facebook, and now my wall is bare. I sometimes see them online but don't want to talk to them even though I do, I feel like I don't know what to say. I have no ******* confidence anymore and I know its from my problems at home. I used to be boisterous and happy and fun to talk to for girls but now all I do is talk to guys and make sex jokes. I like hate my life sometimes and my hormones and teenagerness isn't helping anything. PLEASE SOMEONE TELL ME WHAT TO DO (p.s. i already have a psychologist, he's like my bff) I feel like if I tell people about my problems at home they might have a little more respect for me and be more understand with why I act like ****. but someone PLEASE HELP PLEASEEEEE
