NO Friendships OR Romantic Relationships! :( What's wrong with me?

I'm mixed, and I've always had trouble identifying with a particular race. My mother is Hispanic and my father is Indian. I grew up in a neighborhood that was predominantly Hispanic and I used to get teased for looking different. :( As the years went by I tried to accept myself for who I was. I only had ONE true friend while growing up, and we no longer keep in touch. Now that I'm in college, I'm still lonely and I often feel...awkward. I live alone and I mean, I literally have NO friends. My family lives in another state, and to be quite honest, we aren't a very tight-knit family (parents divorced when I was ~11). To make matters even worse, I'm 20 years old and I have never had a boyfriend. :( I'm always the shy girl in the room, avoiding eye contact, and secretly wishing to be invisible. I've heard people say that it gets easier to make friends as you get older, but as far as I can tell it's just as hard if not harder! I feel like I'm living in this world where all I do is coexist with other people, but the interaction is minimal. I want friends. I want a boyfriend. It just never happens for me. What's wrong with me? :(
