I have never met anybody else in my position, my DM is intellectually disabled (and I strongly suspect she has undiagnosed ADHD as my son and I have been diagnosed with it)
She is barely literate and thinks/speaks/acts like a child of around 8 years old. Sadly, whilst she has some endearing qualities she is quite bigoted and rude, having adopted my old fashioned grandfather's mindset from decades ago.
I was approximately that age (8) when I first realised she was different. I found out through relatives that she went to a 'special' school.
Social services were around in the background due to her limitations but were completely useless and after my grandparents died (they guided her through parenting me) I was badly neglected when she became solely responsible for my care.
She didn't know how to cook so we lived off microwave meals or frozen beige foods. I had to deal with all mail, bills, letters, helping her with absolutely everything.
She didn't know how to parent me and spent her days shouting, swearing and ranting.
I remember feeling so confused and embarrassed as a child as I realised she was nothing like my friends parents and I ended up isolating myself.
She moved away when I was 16 and became an alcoholic.
I got back into contact with her some years later, as an adult, and have been able to view her more sympathetically but struggle massively with how rude and inappropriate she can be. After having my own children and realising how things should be I can't help but feel really sad about the hand I was dealt (her too - of course)
I've never met my father, it was a brief relationship she said, and now with the benefit of hindsight I can see that she was almost certainly taken advantage of. Age of consent aside - she is too vulnerable.
I'm not her only child but I'm the only one she raised. My brother, who had a different father (another exploitative fucker no doubt) and got adopted from birth. He fortunately had a much better life.
Me, my DH and our DC have just got home from a holiday which we took her along on (shes 3 years sober) and I found it so stressful, having to guide and parent her alongside my DC. I look out for her where I can as she's getting older and can't navigate things like bank accounts and all other life admin.
Talking to DH afterwards he expressed how incredibly rare my situation is and how he had never met somebody with a parent like mine before. He found the trip incredibly exhausting, then he felt guilty for feeling exhausted by it aswell.
My DC are fond of her (my eldest especially as he has additional needs himself so they have connected) and I facilitate a relationship with firm boundaries in place (no shouting, swearing in their presence etc) but that too is exhausting as I'm constantly on guard waiting for her to say something inappropriate.
I'm not without issues as one would expect growing up with absolutely no parenting provisions but I haven't done too badly and consider myself a relatively good person and parent.
I realised today that I would benefit from accessing therapy to talk through it all.
Does anybody here have any experience of a situation like mine or has come across anything similar?
