I agree with Frib...
Okay, you're 15, right? I was depressed at that age also...I felt lonely, abandoned...everything...it's just a phase almost every singe teenager go through... It gets better after some time...especially if you find someone (girlfriend...) who is returning the love to you...at least that's what happened to me...I fell in love and everything got better... You just have to wait a bit and keep in your mind that it's gonna get better...
Yeah, I'm something special also...I could see some similarities between us...I'm also quiet and stuff...and weird...lol...
Anyway, I don't think you have developed a serious depression...which doesn't mean that you aren't depressed...but it will pass, I'm sure...keep your mind positive! :thumbsup:
Wish you best...
Oh, and I'm also here if you ever wanted to talk to someone...I also know a bit about psychology...I'm interested in it and have lessons at school... I also like to listen to people...
