Dude,
don't even think abt suicide. Your life is not the problem......your problem may seem larger than life to u and u may think there are no solutions. But trust me.....there are solutions to yr problem. May be yr dreams have fallen apart, may be failure in something has made u so hopeless but my friend, make new dreams for the older ones, life always doesnot move on as we expected, but we can adjust our goals and still be happier.

Personal note,older brother of One of my very best friend from school who happened to be my neighbor too,  hanged himself up. I have seeing  the horror and dysfunction in that family for years now. They were never the same people. Scars of such tragedy never heals and his death created more problems than he set out to solve under a tree of sundarijal forest.
Love yrself and love yr family and friends.
