I had seriously considered it in the past. I went through a pretty rough time at school, what with bullying and all that. Certain friends I had started shunning me for no given reason, which just compounded the problem. I started feeling increasingly isolated. I think this about three years or so that this went on for.
But when I seriously considered it, I realised that there were still my family and friends that hadn't turned their back on me that would've been affected by it.
My Dad once said something on the subject (I think we were discussing Kurt Cobain at the time), and it really stuck with me. Suicide is a permenant solution to a temporary problem.
And he's right. The problems I had were temporary. I moved from school to college; the bullying stopped, I made friends - better than those that shunned me. Looking back, I feel kind of stupid about the whole thing, as there are loads of other people that have it much worse than I did then...
