same here. one of the most upsetting things she did happened about several years ago. I had just gone through a divorce and moved home with my son. i got a job that required more than the standard 40/hrs a week. i was working my way up the managment ladder and had to be flexible.
typically my mom would pick up my son at preschool/daycare because i worked late and over an hour away. This particualr night i had to work 7 AM until 11PM because a new project was starting and i was in charge. I had asked my mother weeks prior if she was ok with this. She said yes.

that night i called her to see how everything was going and to say goodnight to my son. She flipped out on the phone.
assused me of being a horrible mother, never there for my son, that she beleved i was not at work , that i must be at some wonderful party doing things that i cannot repeat here.

all i could do was cry, i was hurting for myself but terrified for my son. If she was doing this to me on the phone what was she doing to him at home. i hung up the phone crying even harder. the secretary asked me what was wrong and i told her. She couldn't believe it she said moms love their kids and she couldn't possibly have meant it.

She called my mother right back to ask what happened and to tell her i was leaving to come home becuase i was so upset. My mom said even more horrible things to her which i cannot repeat. So i raced home to protect my son from the Witch.

When i got home she was surprised to see me. She very calmly asked me why i was home when i referenced the phone call, she said "oh honey i know you were working. you didn't have to come home right now. i was't really upset i was just tired from babysitting so much."

my mouth dropped and i could say nothing. I carried my sleeping son into my room (for protection in case the witch reemerged) and tried to sleep, wondering what retribution would be waiting at work in the AM for leaving early.

i have enough storied like that to fill these forums but even when i recount the extremes my mother has put me through they sound so far fetched, Like the secretary said moms love their kids she couldn't have meant it .
