I feel unloved and lonely?

[Natasha M]

I feel really lonely and like I have nothing in my life to make me happy. Most of my time I spend on school, I don't even go out much anymore or do much of anything else. I am also very shy so I have trouble making new friends. I have some friends from junior college and high school but they are really busy so I don't get to see them much. It seems nobody cares about me, I am having problems with my best friend right now so it makes me feel even more lonely
Every time I go on Facebook, I see my friends who are married and some who also have kids and it makes me sad because I feel like I will never have that. It seems like I have nothing going for me. I am in my mid twenties and going to turn 30 in a few years and I haven't accomplished anything in my life.
