Is there a way to 'beat' loneliness?

[bhrc]

I kind of go through these phases where I am on top of the world and then seem to jump off the cliff (unintentionally) into this dark void of loneliness. I guess its normal to feel this way sometimes, but its sort of why I joined this site originally. I think I feel like I just don't have the people to talk to. Yes, I am engaged to a great guy, but I feel like when I talk to him about this he doesn't know exactly what to do. I feel like making friends and talking to people is his bread and butter, so I think I get jealous of him and that's why whatever he tries just doesnt help to make me feel better.

Does anyone know how I could climb out semi-permanently?
