My mom didn't want me?

I've posted about this issue before but its gotten worse i just need to vent😔 sorry for the long paragraph

For starters im 18 and I just got a job because I'm trying to move out and i don't know how to drive yet. My dad takes me everywhere i need to go but I hate having him taking me everywhere because he is disabled and goes to dialysis 3 times a week plus he's working to get him a place since him and my mom split up. My mom makes up excuses whenever I ask her to take me somewhere or teach me how to drive. She always says she's busy but i know shes going to her bfs house🙄 My relationship with my mom has always been the best we always did everything together we watched movies in her room all of the time went to the nail salon, shopping pretty much everything. I have 7 other siblings I dont have that great of a relationship with most of them we barely get along or talk especially since they've all moved out, I've always gotten the feeling that they don't like me but I've gotten used to the terrible treatment. They put her through some crazy stuff over the years and it sucks because she jumps up and does whatever they need her to do. I never gave her issues growing up but whenever I ask her for something she makes excuses. Wednesday I had a really bad breakdown I've never had one of those before but I ended posting a status on fb saying "I feel alone I need help and I have no one." My mom commented "you never communicate thats not my problem" which is a lie because I tell her everything but she brushes it off and makes excuses or ignores me whenever she's on the phone with her bf. So I've stopped asking her for stuff now she's upset at me and hasn't talked to me since I posted the status. She's been calling the family telling them that its my fault I don't have a ride to work and that i don't communicate and she doesn't care because she's been busy doing what she needs to do and basically bad mouthing me to everyone which is the reason I never tell her anything anymore because it never stays between us😔 now my dad has to change his schedule for dialysis to take me to work every morning and pick me up until I learn how to drive. (I've been thinking of buying a car to practice in) but anyway my bf was in the car with my dad and he asked him a question and he told him to be honest and he asked him "did y'all (referring to my parents) even want her because yall don't act like it sometimes" my dad responds "when her mom was pregnant she was going to have an abortion because she already had so many kids but I wanted a child so I told her mom to keep her so we made a deal that I'd take care of her since she'll be my child and she doesn't have to worry about it." My bf told me the conversation and I didn't know if I believed it or not because both of my parents talk bad about each other but the way my mom has been acting since I turned 18 adds up to what was said. It hurts because it really feels like she doesn't like me like I was a problem for her. Looking back I remembered all of the times that I needed something and she told me to call my dad or if I had an issue she'd call my dad and he'd have to talk me through it. I've been thinking a lot about it and im starting to believe its true part of me doesn't care but the other part is upset thinking that our close relationship meant nothing 🙇🏽‍♀️ I dont know how to feel anymore im just going to go to work and save up some money until I can move out so I won't have to deal with anyone from this family anymore

Thanks for listening 💜🥺

Note: my mom doesn't work so she always at her bfs house or at home
