My grandmother was a paranoid schizophrenic also. She would do and say some strange things.....I feel so bad for my dad who was raised by her....but mostly she was a very good mother. Unless you "really" got to know her, you would have never known or suspected what she dealt with internally. I often wonder/worry that I might have the same thing but my doctor thinks it's the bipolar symptoms causing the seemingly similar thought patterns. I'm sorry you and your mom dealt with that.
