I feel upset and sad and angry.

I was going to my daughter tomorrow, see her and my 2 li'l granddaughters again. I was really looking forward to it! Haven't seen them in over a month as I had to cancel a prior visit due to a cold sore.

Now my daughter asked if my mum was coming with, which I hadn't counted on.
I've had some huge fall-outs with my mother of late. She's losing it and I bear the brunt of it. She's never been loving, understand, and appreciative of me, more that I've been used as her emotional crutch all my life. Even as a young child.
The manipulation & emotional blackmail I've had to endure are unbelievable.
As it is, I just can't and won't put up with it any longer.

But her abuse is getting worse now she's losing it.

Long story short it resulted in me now having to wait yet another day to see my granddaughters AND take my mother with me. Which is the last thing I want.
The way to get to this new appointment was far from pleasant, another escalation and more abuse.

I don't want to involve my daughter in all that chit so for now I'm leaving it as is.
But not happy.
Stress, sadness, which I immediately feel in my body.
Aching muscles etc.
And very sad she messed up my happiness about seeing my granddaughters tomorrow.

I know it will sound harsh to many but after all the abuse I've had from my mother my entire life I truly wouldn't mind never seeing her again.

The way she's losing it is fast. Not that long ago it was possible to have a decent conversation. No longer. She's not interested in anything, blunt enough to say that, cuts you off mid-sentence as she feels you've talked enough and she's entitled to speaking, never apologises and so on.
She's always been kind of like that, but now it's 10x worse.
And she's only beginning to get dement.

I've read this was hard on family, but bleep me!
If it is going to mean abuse abuse abuse, I am not sure what I'll do, but likely not go anymore.

Anyone else had similar experiences?
