Why? What's wrong in yrou life that you cannot face it?
Hell is real and so is Heaven. If you no longer value your life, you have nothing to lose, give it to JESUS so you can fullfill your pourpose and have rest and peace when you die.
Because you know that it's not the right time and you don't want to hurt others as much as yourself.
I've been there and at this time, I'm glad I didn't. It's tough being your age. However, you're tougher than that. Live and find a way to overcome your current issues.
