Is There Such A Thing Called A Best Friend???

Have you ever felt so lonely even when people say they're be there for you when you want someone??? Yeah well I feel that everyday. I don't have a friend who I can talk to about the more personal stuff because when i want to talk to "the friends that say i'll be there for you", they don't care and they won't understand. Lonely lonely alone... I used to have a diary that I would write all my personal stuff and secrets cos I don't have anyone to talk to. I had kept it for 4 years and 6 months and last weekend, I burnt it because I though "whats the point in keeping this if noone's gonna read it or understand it??" I've always dreamt of having a best friend, and I know its weird but its true.

I just feel sad, trapped, frustrated and angry with myself :/
