Hard subject for a forum, however i used to know a couple of people who have now gone that way, 2 years ago my nephew went age 22 over a GF who messed with his head.
I can feel where he was having been very close to doing this myself, the desperation you feel when you see suicide as an option is almost indescribable. It feels like a relief that the pain is almost over, you hold on the best you can but you can feel your grip on life slipping away.
I was lucky as my family were there for me and i recieved the help i needed from a good GP before it was to late. I was told that i would start to have some good days in with the bad, it takes a while living one day at a time but you soon have more good day in a week than bad. In time the bad days are few and far between and you learn the skills to deal with the bad days when they happen.
When you come out the other you begin to start knowing who you really are and what is important in life.
