The closest I came was sitting alone on a beach wishing I had the courage to walk into the sea. I'm not going into the back story too much, it involved my divorce, money worries and a family trauma all happening together. I felt totally alone, and I seriously thought everyone would be better off without me. It was, however, the lowest point and I am so glad now, that I pulled back from the brink.
One thing though for me it wasn't about wanting to die, it was about no longer wanting to live the life I was living. And I know the simple answer, is well change your life, but sometimes it just seems too big a hurdle.
