Sorry this is long but I am at my wits end.
I love my mother but she has a lot of very difficult personality traits, very narcissist traits and her behaviour is having a significant impact on my health and that of my dad and sister.
There is a massive backstory that would take me hours to write out but in short mam and dad never had a good marriage, lots of arguments, her not talking to him for days on end, stomping around, always tension. She always ran him down to us, wanted us to take her side etc. Dad can be a bit useless in the sense that all the responsibility fell to her and she got very bitter over it.
The last 2.5 years have been very difficult, dad got 2 cancers and required surgery and 8 weeks (5 days a week) of radiation therapy in a hospital 1.5hrs drive away. There were honestly about 80/90 medical appointments over the last 2.5 years and my sister and I have to organise them all as mam refused to do anything.
She claimed she wasnt able, couldnt drive, couldnt hear, etc basically anything to get out of helping dad. This was all new to dad after never having anything wrong with him and he really struggled.
He got the all clear in Sept last year but unfortunately in Oct his health went down due to another medical condition. The last 2 months have been extremely difficult, dad was hospitalized 4 times, nearly died twice, it was very much touch and go. During his hospitalisation in early Feb mam had an epiphany and decided she would be nice to dad, she actually did love him, she lamented the bad marriage, things would be fine from now on, she would look after him, etc.
I knew it was because she thought he was dying but if he ever showed a sign of improvement she would turn and she did last week when finally he started to recover. He is very weak, needs some help with daily activities, cant do chores, leave the house, etc. She is constantly tormenting him and refusing to help him. Examples are:
not making his hot water bottle for him at night even though he could risk burning himself and is weak, not organising his tablets (he finds it very confusing to know which ones to take), refusing to take his blood pressure anymore, only cooking a small meal for him and cooking food he doesnt like (he is massively underweight and needs to gain a stone), complaining about washing up his dishes, going out for hours and not leaving any food for him or fuel for the fire.
Its very abusive behaviour. My sister has been an angel, she calls to the house 2/3 times a day, does all the medical appts, has given 100% emotional and practical support. She called my mam out on her bad behaviour last week and since then mam is refusing to speak to her and has upped the ante with her carry on.
My sister has 5 kids one of which has SN, she is struggling. I work full time and am very busy with my 3 kids. I suffer with a panic disorder/anxiety and her behaviour is affecting me mentally.
I would happily call her out on this but when we have done in the past she takes it out on dad. She refuses to talk to him claiming its is because he is telling us tales, she creates havoc when we stand up to her.
If it wasnt for dad I would probably have nothing more to do with her. The problem is the effect on him, he just wants a quiet life. I have offered for him to come live with me but he doesnt want to. He has friends over to visit and has his garden. Mam is rude to his friends but they are used to it and ignore her.
I feel so much anger towards her for making dad's life so hard. We have a palliative care nurse starting to come this week. It is hard to know how much time dad has left. The new meds have helped but it is a progressive illness and he will die from it sooner rather than later.
How do I deal with her in a way that doesnt impact on dad?
