I think I may be depressed. And it's nothing like when I was younger and was sad for attention. I'm confused and I feel very alone.

Well maybe I'm not "depressed." I mean I'm happy when I'm around other people. I'm perfectly fine. But I've been by myself a lot lately, and it's made me very sad. I'm not close with any of my friends here anymore, except for one. I feel like there are only two people I can talk to, and when I need to I can't. Promises and I Love Yous and all are nice, but do they still mean anything after being apart for so long? How can you tell anything is still there when you can't see somebody?

Being alone makes me feel insignificant and unloved, but I'm being completely anti-social, so it's mostly my fault?
