"If you don't have your head on straight enough you can really be convinced you are going nuts."
Yep. My mother was a chronic alcoholic - But also an untreated nut.
My husband felt the need to tell me "You're just like your mother". When I, *sober*, asked him, *not sober*, to leave.
He NEVER even met her. It just flooded in my head all the times he called me paranoid and insecure.
