No, Slash is telling the truth and you're exaggerating. I've been in Slash's shoes, in a way... Not in the situation itself, but I've had the same moodiness...
When I was battling with suicidal clinical depression, I nearly passed on several times. Feeling upset over a single girl liking a different guy....

that's cute. I remember when I was your age, I would ask maybe 10 girls a night to dance at the high school dances... Get turned down by 6, but keep trying to find someone.
Yeah, I guess, now that I think of it a bit. Although what I will say to add on to this, I'll mention it elsewhere.
Where?
My advice to you; live your life happily. Girls - like guys - want to be happy. Do you want to be around someone mopping and sobbing "woe is me! I have emotions. This must mean I'm clinically depressed and suicidal!"
No, no you don't. You feel guilt-tripped if you don't, until you find out that they're faking it for attention and then drop them on their lying faces.
But, the happy ones... The "silver lining" people... Everyone likes them.
Be the silver lining guy for two weeks. Try it. Since I've began to be this guy, I'm happier. I'm more successful. I don't even mind being single as much, because I can be as picky/choosy as I want. I've got the job I want, I've got a wonderful relationship with my parents and I'm generally getting closer to achieving my dreams.

Last night, a friend of mine was being the melodramatic "playing it up for attention type." I asked what was wrong, suspecting she was. Anyways, despite the fact that she was, she quickly played it off.. we got to talking... I mentioned my ex-gf (first love/only true love) to see if that was why we had stopped talking. While it wasn't, I got to thinking about her again. I haven't seen her in three years, but I still love her.
This is probably why I can't find anyone worth dating... None of them are good looking enough.. None kiss as passionately. None talk to me in the same sweet, soft tone.
Well, just the one... The one who treats me terribly and has a boyfriend.
I'm probably screwed; might not be able to move on for a long time
