OMG!!!! I'm soooo sorry about your MIL. Can anyone be that crude, obnoxious and hateful? I guess so!!! Please don't let her get any satisfaction by knowing she's adversely affected you....and please be careful with your disorder. Try to stop it now before it really gains a foothold and consumes you. Take care

I could swear you were talking about my father's lovely bride! I too let this woman let me get out of control by the word she used to hurt me. What I realized is that she hurts everyone form the guy bagging the groceries to the person she is suppose to love, my father.
She has said some winners over the years to me and my kids especially my dad. She picks on him about everything that goes into his mouth, orders for him at a restaurant and calls him a slob of he gets crumbs on anything especially himself.
We were at a local amusement park and she told a woman with a child having a temper tantrum it was a no tantrum zone and could she please shut the kid up.
She told my whole family that my son would be having hi Bar Mitzvah in Israel because my dad was going to pay so she was looking forward to planning it.
She told my brother's wife who was pregnant that the reason she and my dad chose not to have kids was because they are o much trouble.
I don't let her get to me anymore for a variety of reason; the most important is that people like her need to make people feel bad so they can feel good. If I let her make me feel bad than she gets what she wants and to me it is no longer and option.
Don't let this woman get to you, it gives her power over your life,
