Often people speak of suicide as a selfish act. For the one who is doing it, me for instance, that was the furthest from the truth. Although twisted, the idea is that if I am removed from loved ones lives, then the pain of my mistakes go away.
It seems to me that pain, the stopping of pain might be the main motivation for suicide. The wt doesn't know what it's talking about when they talk of selfishness. But then, the wt doesn't want their people to ever think of or for themselves, anyway. I'm glad that you are finally unloading this burden. It takes courage and honesty.
