How to not be lonely?

Ever since i broke up with my beau(boyfriend), i have been so lonely. Yes i have friends, and family. But still my friends will not answer texts, emails, ims, or calls. I don't do contacting a lot at all. I have been getting depressed really easily, because of my loneliness. My family is parted, and my friends are not supporting me. Not even my ex will talk to me let alone look at me. What do i do? I hate being depressed.
