I've yet to attempt suicide. But I thought I'd post here anyways since I've come pretty close before.
I started having suicidal thoughts when I was 15 or so, but they weren't serious until I was 20/21. I came the closest to going through with it at 24/25. I had just broken up with my boyfriend and also had to move back in with my parents. Both events made me feel like a failure and like I'd never get my life together. So I went through the process of buying a somewhat expensive suicide method, truly believing I would use it soon. I never did of course, but it's hidden away in my closet should I ever choose to do so.
I'm 26 now. I'm not quite as depressed as I was at that time, but I still often feel myself slipping. Sometimes I'll go into my closet and pick up my method, contemplating whether I should use it or not. However, there is always something that holds me back from using it, whether that be guilt as to how it would affect the people around me, or the fear of death itself. At this point I'm not sure I ever will attempt suicide, but I still think of it as a kind of last resort option.
