Sorry if this sounds harsh now but suicide is by far the most stupid thing to do.
It is a "first wold problem" to find acceptance, friends, joy and if you "fail" at this, you become ostricized, lonely, sad.
You withdraw more and more from society and become a still water, run deep, but in the end you just want attention and affection.
To commit suicide as a final approach of getting this attention and forcing your community to think about yourself, your circumstances, your behaviour or what else (religion/feelings/life etc), but once you are dead YOU get N O T H I N G from it!
To those people who really think about this: if you want to change your life or the world around you, do something meaningful, but don't throw your life away!!!!
We all die eventually and might end up at the same places or not, but we don't know this for sure (some believe in this, others don't).
The only thing we know for certain is that we live, we die and that this time is limited. So take advantage of having a consciousness and do something productive with your life.
Really, beeing 15-25 years old (+/-) and thinking about killing yourself is definetely not worth your time.
I know life can be really, really hard (I know about people who tried killing themselves), but seriously: take your courage and find a (maybe new) meaning for your life.
If you're thinking about death, don't spend your time thinking/worrying about how/when you die, but how you live until then.
I'm afraid of death, because I don't belive in any religion, redemption or afterlive and this is the reason why I want to make the most out of the time I have been given here.
