I'm sad. And I'll tell you why

NO ONE is helping me. I posted some lyrics which have been stuck in my head for MONTHS on the other board, and NO ONE is replying. I am very sad right now.

by the way, I wanted someone to tell me what the song was :). Forgot to tell you all that. I'm still very sad :(

hehe YAY someone is here! I hope no one shouts at me for posting it on here, but is a sadness and depression board, and it's making me sad :( honest. It's something like:
I can't live, without you, know i did you wrong boy/girl, know I did you wrong still....
It's quite fast and I think it's rnb... ANy idea??

I looked, but I'm sure everytime the song comes in my head, it's slightly different...maybe I made it up??
