Stuck in a corner

Just need too vent really and ask what would people do if they were in my situation.

So a year ago my grandad passed away and we made the decision too stay with my nan so she wouldnt be on her own as she had NEVER been on her own so option of a nursing home was never choice and still isnt now!

My nan is 95 years old and still able too cook, shop and have a conversation just she dosnt want too be on her own and we dont want that for her either.

This has been a major change in my life the fact that i lost my grandad who i was very close too and then basically living with my nan half the week.

Around this im a carer as my job and work 4 days a week as well as staying with my nan 2 or 3 days a week which means i have too stay on my days off bcos i work shift work.

I have my own house which i barley spend any time in and i have a partner of 9 years who i barely see now because of this. I have no children but this is something i want soon?

But what is the hardest part of this all is my mother.

She is so controlling and angry i literally get it off her all the time

She kicks off if she is not happy with the amount of days she has too stay or has too stay a particular day.

I work any day through the week so weekends is a day a often work with having 1 in 3 off.

I cant go abroad which is something me and my parnter did 3xs a year.

Because she is so unhappy in her life i feel like she feels like i cant have any joy? I literally feel like im a child and not a 36 year old woman with her own life.

This has effect my partner who is infuriated with the way she treats me and talks too me and says she is controlling both our lives and is effecting both our mental health.

Im going away for a few days for valentines which we always do but normally we would go abroad but were just going some where a few hours drive.

I deceided not to tell her that i was going away and i was i work which i often have too lie too her or not say im on annual leave.

I just felt like not telling her was right on this occassion as i normally get the i dont go away blah blah blah (shes married and has plenty of time too when i stay at a weekend).

So i gave my stays and she kicked off.

She couldnt stay bcos she had work a few hours away.

I told her i couldnt stay so my nan would have too stay on her own for 1 night where she contiued too repeat herself.

I feel like she does this too make my break and give in but i wont bcos i had stayed 2 sundays before so i stand my ground.

My partner feels like i should say something or stand up too her which i do but what can you do if someone dosnt listen? Because no matter what she dosnt listen.

I have an auntie and uncle, my auntie does 2 nights but travels down but my uncle lives abroad and comes when my aunties there or when im in work so dosnt really benefit me really!

My mum see her partner every day aa she stays with her, my aunties see her partner 5 days a week whilst shes home and i barley see mine as he works nights too which is hard.

Im in such a hard and difficult situation what would yous do or suggest? Would you stay at all?
