mother doesnt care about my daughter

Sorry this one is quite long. Bare with me!

So I had my daughter in March and she was born with undiagnosed down syndrome. My "mother" was there and seen her come into the world. She was the one who highlighted the characteristics of d.s. 

The first month or 2 after she got off cardiac ward, i was packing up all our stuff (she was sent home oxygen dependent so i had a tank and wires/tubes and SATS monitor on top of normal baby things, sterilising bottles and filling up all the formula containers) and getting us both dressed and washed and out the door (leaving my dog at home in her crate for hours) and my partner would drive us there before starting work at 11am, so it was a crazy rush in traffic and he was ending up late for work and getting warnings. When i was going into my mums house she would pretend to be sleeping on the sofa, through the dogs barking and even through the baby crying🤔 so i would just sit there and wait on her to wake up. She would hold her for a few minutes and would be done, my younger sisters were the only ones that loved seeing her. 

So i was like, screw this. If they want to see her, im not going through all this hassle to be sitting doing what i do at home with nobody bothering with her and not feeling guilty about my dog being locked up all day to suit these lot, plus my partner getting in trouble at work.

So i stopped running to them and they didn't once come to see her. I've lived in my new house for 5 months and my mum has been here once for an hour then rushed away and pretended she had to go do something. 

They bought my 18 year old (golden child) sister a 16k brand new car recently and she was here 3 times in 5 months. Bare in mind i never got a damn thing, i was cinderella, i cooked and cleaned and minded their children because i was "a stupid piece of shit that would be on benefits anyway". My mum took all my pay when I worked and still received benefits to keep me. Sanitary towels were literally a gift. 

The last time they seen my daughter, she cried hysterically and didn't know who they were. 

So about 5 weeks ago i lost my shit. I called them out. Something I've done before for the mental abuse and slave treatment i received as a child and was cut off completely. They told everyone I lost my mind and Id claimed they all abused me and related it to a famous (extreme) UK child abuse case called 'baby P' & laughed about it with everyone.

So it took alot of courage to call them out, knowing i would lose them, face criticism, being the talk of the family, called crazy, cut off from my young sisters and my baby never seeing them or having a great bond with her aunts who i raised and love dearly. were all just caught up in this mess and the kids end up hurt. 

I asked why nobody makes an effort to come see Ana. She's a blessing, we treat every milestone like its Christmas, she's a true treasure we adore, yet they don't bother. We live 5 minutes apart, there's 4 cars at their door, whats the deal with that?? 

Well didn't I just kick off world war 3. 

My spoilt selfish sister (with her brand new car & doesnt pay petrol for it because shes never worked a day in her life), told me to get off my ass and pay cabs!

What??

So ive to go through all that hassle and fork out money and leave my dog and new puppy crated up to sit in their house, while they barely hold her or anything? 

I bit my tongue too long. This is my precious child I've waited years on. The promises I've made my daughter.  il be f**king damned if il sit back and allow her to be treated second best, like she doesn't matter. Nope. I told my sister all i wanted was for her to treat my house like her second home, like we always talked about. Come to my house, connect to WiFi, watch Netflix, my fridge and cupboards are always full, my house is clean and her niece is here! What is the problem???? Why does mum not answer my calls, yet answer when i call her withholding my number??? Why does she pretend the phone blows up in her hand to hang up on me? Why does it take her 4 days to respond to my texts? Why does she not acknowledge her first granddaughters pictures/videos on fb? Why does she not bother to see her or ask about her?? 

Within minutes, my mum lands at my house, i opened the door with a smile, so excited thinking "god, shes here! She's here to spend time with Ana!" 

She screamed in my face to leave my sister alone! That I need serious f**king help and that she had already lost the child???? 

Then she stormed off, jumped in her car and spun her wheels, smoke all over the street and my neighbours came out thinking someone's car was just stolen. Theres young kids in my street, she could have hurt someone or mangled someone's car. 

Im so sick of her selfish behaviour. Im sick of her blaming me for everything. Im sick of being treated like im nothing and her telling everyone IM crazy. 

Its been over a month and my daughter doesnt know who my family are. I feel like I've been shunned. My younger sisters don't know whats going on, just that im not there to see them & they miss Ana. 

My precious daughter doesnt even know they exist. Not so much as a text from them to ask how she is or how her physiotherapy is going or anything. 

Now i feel like Ive done wrong. That I need to apologise for acting up. This sucks. Any advice is welcome 😞
