To die gives you nothing. You dont exist anymore and it will be painful and your family will miss you. One day you will die, let the nature/god take your life, no need to do it by yourself my friend.
I know many things sucks in this life, but there is also many good things. If you die, you will never eat again, never drink again, never see a movie again, never feel the wind again, never listen to music again etc.
Enjoy the good parts of life and meet up with a psycholgist.
