I'm so stressed and lost

I'm about to be 19 soon and I've made the plan to move out of my parents house when I first hit high school. I've been saving money since then to get a car and an apartment and about 7 months ago me and my bf decided to get an apartment together. He was saving but things are starting to get difficult. Sorry in advance for the long paragraph but I need to vent 😔

First off he was living with his aunt a few months ago until her house burned down and he lost all of his things so my mom said he could stay here until we find a place to move into. He has a job but his hours keep getting cut and we can't seem to get a job that pays enough or gives enough hours to keep up with the bills if we get an apartment. I've gone to interview after interview with no call backs I've called and bothered the jobs a lot and im honestly planning on showing up at the jobs to show how serious I am about being hired. I've been asking my mom if she could help me find a car and teach me and my bf how to drive (which I've been asking about a year for) since she doesn't want to take me to work if I do get the job and my dad is struggling trying to get into his own apartment (he's older and has kidney issues and living in hotels until he can get on his feet) and I don't like to have him take me back and forth everywhere when he has dialysis and works as a doordasher even though he doesn't mind. Anyway my mom always comes up with excuses as to why she can't take me driving (she doesn't want me to wreck the car, I don't get up early enough, she leaves to her bfs house so i dont see her for days, or she wants me to pay for a driving school which is expensive and its going to take away from my savings for a car) I've been looking for cars on my own to go and look at to teach myself to drive but I don't know much about them so I don't want to buy a car that'll break down on me. I'm not sure what to do I feel like all she does is criticize me about every little thing ever since she became open about her 4 year relationship (that she just told me about months ago...but I already knew). Its like her bf doesn't want her to help me because everytime I ask her a question while he's on the phone (which is all of the time) he gets upset at her and she shoos me away until he gets off the phone. Its hard trying to do all of this when I don't know what I'm doing. I really just want to cry because I know I could never talk to her about it because all she does is yell and only sees things from her perspective. My siblings don't really help me with anything even if I ask they just brush me off or ignore me. My bf doesn't really have family so he is in the same situation as me. I feel so alone like everyone in my family is against me. I literally sit in my room and stay away from everyone because they all treat me weird. I feel so lost like everything's falling apart and that I'm no where near close to the finish line😔💔 thank you for listening 🙏
