Try and understand it possibly from that perspective. Research it, and learn from it for yourself and teach others. Help others not to go there. I think if your father had a second chance he would agree to that. When you take your own life though it is too late, you can't change it or take it back.
Death is finale.
Life at times for everyone is a battle. Everyone walks the tightrope. Be careful and keep yourself in balance. Seek out help, counseling and love from the right professionals and family a caring family member. Life will always have its ups and downs.
