Toxic family in 20’s

So I’m 22 soon to be 23. I work at walmart and every month half of checks go to my mom for bills, gas in her car, food, anything at the house. I have yet to move out of my moms house, because I’m continuously broke. Meaning after the money I give her that ranges from $400-$600 a month ( two week pay period).

I’m left with $200 of my check to use, between uber and lyft. Since I don’t have my car or my license yet. I’m not afraid to drive I’m actually excited about driving. But my car cost 3,000 to repair. Every time I think I have the money. It seems as though I pushed back further from my goal and saving money.

Then at times the little money I have for myself ends up being used towards my brother, and my mom’s significant other ( her man). Along with other expenses she wants. Plus I’m told that “I don’t cook, clean or help out around the house because I sleep all day”. I work 4/5 sometimes 6 days straight and do school one day a week. Also pay out of pocket for tuition money( which is my choice). Do you know what it’s like being hungry and your card saying declined and deciding to not eat, just so no one knows your broke. Or having a coworker buy you lunch and food knowing you wanna cry and break down and just give up?
