I feel
for you ... I have a Mum who is very similar ...
My Mum is what used to be termed as 'manic depressive' and was on medication from a teenager, she's also an alcoholic. Growing up wasn't much fun.
She would veer wildly from cloyingly loving, to nasty and violent. There were several suicide attempts ( mainly to get attention, she'd take pills, then go straight out into the street and tell a passer by, so she could get to hospital)
She lied about having cancer, she faked a heart attack, she would turn up to meet me from school pissed, she attacked me the day before my wedding, then attacked my brothers gf, after years of shit it just looked like it would never end ... but then i had kids ... she then was banned from being around me or them drunk
I felt no guilt
My poor brother took pity and had her over to stay with him ( i had sheltered him from a lot growing up, big sister !) and she repaid him by stealing and trying to throw his wife down the stairs in front of their kids - awful, awful, awful ...
I felt no guilt
She is not allowed to ring our house if she's had even one drink - we ring her on special occasions ...
you guessed it, no guilt, it's worked out better than i hoped as i get on better with her now than i ever have.
With the space and distance i can see she is ill and won't change, and i understand that.
Best of all my children are protected ( by distance more than anything) so i do allow her a relationship of sorts, they love photos she sends and packages of cadburys and have NO idea that she can be a nasty, nasty drunk. I'm proud of that and the fact i've let some of my anger and bitterness go, it hasn't been easy though and i'll always wish i had a proper 'Mum'
