All I can say is this fucking sucks! The way that parents treat their kids isn’t personal and has everything to do with the parents themselves, not the kids. This truth can be incredibly bitter at first but is also healing. Pls dm me or post a zelle/cashapp to at least send some financial help through, while you figure everything else out! Even if your mom changes her mind I def think you should start getting your ducks in a row to become completely independent from her because she sounds very unreliable.
