Not all suicide reasons include getting even with others. I personally don't like the term "selfish" either. We were taught many things were selfish, when indeed, they are not. IMO the thought of suicide is for a way out of something... making something stop, to end it. I have no anger issues with others when I consider such a thing... it's all about ending the pain and suffering. And while yes, that might not be considerate of others, they aren't trying to live with what I live with, either.
I am still around because of my T. While consideration of his feelings are not usually in the mix, I am "programmed," now, to call him, and once talking with him, remember his professional involvement in my welfare. I guess it really is his hope for my future that keeps me around
I think one could make that attachment and connection with those at the ER, too. They can get to know you, and help you through tough times.
