Suicide

Life doesn't equal running around in high school with your fake little girlfriend that you are only with because you want to show the other fake little people with fake little girlfriends you also have the ultimate "trophy of maturity" (a fake relationship with a girlfriend who is just trying to impress the same fake little people you are). Don't think that just because you're not the pinnacle of popularity in high school that you are doomed to a life of misery.

Just wait it out. Don't go looking for a relationship, because then you're just going to end up settling for one out of desperation, and it is going to end bad. Just keep going through things and eventually, the right girl will find you. It's the same with true friends, except a lot less sexual.

You're being really rude to this guy. You don't know enough about him to call his life "fake" because he might really just be entering the dating game; lots of dumb $hit happens to people that date in their mid-20s, fake has nothing to do with it. In any case, beating on a depressed guy -- 15 or not 15 -- is just plain not nice and you should cut it out.

OP: Suicide is usually brought on by really traumatic events and clinical depression. For example, a German multi-billionaire killed himself after the stock market crash because he lost a LOT of money. Other people are unable to survive the death of a loved one, (father, wife, etc.) However, suicide is never a good solution because time heals things, your situation stabilizes and you get joy from things in life that you probably haven't even considered yet.
