Well having tried and thankfully failed it's so so easy to fall into the trap of thinking that taking your own life is the only way out.
Asking for help isn't a sign that you have failed in any way in fact its shows that there is a inner strength and you want to move on. We all need some pointers in life that can help us find our way through the maze of life.
Working as crew with the disjoined life style that can develop it’s possible that a low situation appears far worse. When you start to feel like you are losing touch with the world and it’s becoming bleak, call for help, it’s really not that difficult.
