I'm just depressing....

I am... I just feel lonely and depressed, and that I'm walking trough life without anyone notice it enough to care if I'm gone... honestly... I just feel that I'm no ones best friend, I'm no ones girlfriend, I'm no ones anything, I'm just here, and for what reason... and I just kind of feel like giving up on my education as well, cause I have no energy to do anything anymore... I just want to stay in bed and give up on life, cause everything just feel so pointless... so yeah, I'm just depressing....
