dbh,
So very sorry for your loss.
I can only tell you, that you are in no way, shape or form responsible for her death.
Go through the grief.
Talk about her.
Comfort her son.
She is at peace now.
She could not grasp hope.
That is not your fault or her other family and loved ones'.
Maybe, stay away from mother for now.
If only people could see the insanity of suicide. But, they just can't see it.
