I'm over my mom refusing to help me

I've expressed wanting to get a job, driver's license, and going to a doctor/dentist for declining health but my mom refuses to want to help me. It's been months and she's still screaming at me for being worthless even though I have no one else in my life to ask and she still believes in this mysterious force that will somehow do the stuff SHE is supposed to help me with thinking that all her "problems" will go away aka helping her own fucking daughter. I'm tired of this. I have no other options and I'm getting sick of how much she hates me just because I want to help myself, but I can't do that if she doesn't help me first. I have no one else to ask. I don't know why she hates her kids so much. She loathes taking them to school, feeding them, everything. She doesn't seem to want to see them succeed. Why do parents have kids with people they hate and then loathe their kids afterwards. If drugs were involved she'd be out the door because spending thousands on drugs is more important to her. She made her 15 year old daughter addicted to weed and nicotine and keeps supplying her with it instead of getting her the help she needs because "meds will make her worse". I don't even like my sister but it's scary and upsetting to see her go down a dark path because of her parents. Sorry about the vent, I'm not really looking for advice because most of it won't apply to where I live or my current life, just frustrated.
