won't bother anyone else

I came here to relate to people with depression and help support the fight,but it just takes one person saying the wrong word to push someone over the edge.I did that to a person and I can't forgive myself.I feel worst now than I have ever felt in my life.I was taught to forgive but have found that some people don't know the word.And I can't go on trying to think everything will be ok.I'm leaving and promise I will not bother anybody else ever.This world sucks!
