Nickey,
u go and have a life. Your mom is not old and unlikely to die. probalby she will not kill herself either, just based on the fact jws think suicide is a sin. Keep in touch, but find support and friends and have a life. And yes, being around someone like that can cause u to become , well for lack of better word, strange. Moving out is a normal thing. u are an adult. u weren't going to spend your life living with her.
U are beating your head aginst a brick wall trying to decide if she knows what she is doing. Probably on some level she does, but she is mentally ill and will probably continue this behavior without treatment.Even with treatment, paranoid schiz is very hard, on the person and the family.It's a dastrdtly illness, and will destroy your life if u do not distance yourselfl form it a bit.
