Distaste for life now?

I went to church tonight and had no one to talk to and It wasn't fun, and its a youth group thing but it was just not fun this weekend. For me its like i'm a smoker and cant taste the food of life, I have given up even worrying about bf/gf bullcrap and I'm never that person that people go up to talk to, Never in my life have I been that one person people want to talk to..there's always those people in that group you want to talk to, i'm getting depressed..and I stopped talking for a few days now and 2 ppl have noticed in my whole life...
