he no longer has to fight his demons. he is free. it is great that he was no longer spiraling downward so he must have started to feel good about himself. Nobody living can understand death. I like to think that when our mission is accomplished, we are freed to move onto something better.
Why are some of us chosen to be mentally disabled and have to struggle to exist with its accompanying pain? I can understand why this is so painful for you. What a shock! Try to be kinder to yourself and gentle for the next while. I am afraid it will stir up more conflict about being bipolar besides the grief you are now carrying.
