Life is an obstacle, life is a gigantic test to see what you can go through, some have better tests than others, I have a decent one, I've had some times that I was not a fan of, but nothing that would drive me to killing myself, loss of family, friends, near death experiences, house fires, junk like that, Sure I lost a good portion of my childhood memories in a few fires, and sure I'll never see a lot of people again, but that's life I guess, not much I can do besides see what else is in store for me, Because each hurdle life throws at you, is a chance to exercise your legs, and get stronger.
I will not pretend to know exactly what you are going through, but believe me, when I say, nothing is worth wishing for death because you feel like you can't go farther, Great men, are made from great hardships
Don't do something as stupid as suicide because of a temporary problem.
In life the only thing that should ever warrant the thought of giving your own life, is if it's to save another's.
I say that only because I knew someone who would have given their life for me, and they said the same to me, that person passed away from cancer a few days after my birthday (And coincidentally 10 minutes before my girlfriend at the time dumped me...what a ♥♥♥♥♥ that girl was)
As I said, and others of this thread have said, do not do something as stupid as ending your one life for anything, you don't get a second chance, and for all I know, or for all anyone knows you may not have anything after that either (Heaven and hell being variables) Push yourself through whatever hell you seem to be in, and better it, be it's master, show it who wears the testicles in the relationship. Look hardships square in the eye (Or cosmic orifice) and make it wet its universal pants in terror at your unwavering, unstoppable, testosterone fueled, ability to look life in the in hard parts, and give it a good 'ol fashion "♥♥♥♥ you I've dealt with worse"
