Feeling like my life has no meaning?

Lately I have been feeling pretty down, like I have no worth to myself anymore. I haven't been myself and I've been feeling sort of depressed. I'm in college but don't really hangout with anyone there. My best friends from high school moved away for college. My best friend rather be involved with her new college friends than me, and now that everyone went away I'm sort of a loner. I'm afraid of asking people to hangout with me. I don't want to sound odd. I do have a boyfriend and I feel at times that he's the only one on this earth who loves me. I have my mom but I don't spend tons of time with her anymore. I miss feeling loved and wanted by people. I hardly feel that from anyone and I'm starting to wonder if I have any worth. I just have my boring job and class to occupy my time when I can't see my bf. I've had a lot of things going on personally and I'm just starting to lose interest in most things. I feel sort of disconnected with people and feel like I don't have a place that I belong in.
