[Rant/Vent] GC sister taking advantage

I'm so fucking tired of all this narc bullshit in my house. Today, I was talking to a friend on skype, when my sister walks in and demands I fold her clothes because she's too busy to do it.

I refused, which started a whole shit fit, she called me psycho, lazy, stupid, and took my phone and started filming me, saying she was going to show my mother. I took my phone out of her hand, and she immediately stormed into her room and called my Nmom.

She told her that I punched her in the face, twice, and pulled her hair. She was fake-crying the whole time too. I tried to call my mom to try to explain and she started cussing me out and telling me to leave my sister alone or she would call the police, and that she's told all the police in our town how I'm deranged and psychotic and violent. This whole time I'm locked in the bathroom with my sister pounding on the door and screaming demanding I let her talk to mom.

After my mom got home, she went to my sister's room to comfort her. Now neither of them has said a word to me and I'm afraid of what might happen next.

The other thing that really upsets me: My mom buys my sister all the expensive things she wants, and spends on average around 500$ (Canadian) per month on food for my sister alone, because a while ago she decided she was gluten-free (she doesn't have celiac's) and I'm not allowed to touch any of her food. Meanwhile, she can eat mine if she wants and I can't do anything about it. I get around 90$ every month for food, which I have to pay for myself because my mom won't let me eat any of her food either.

A while ago I checked my bank account and my balance had gone from 50$ to 10$. She went onto my phone and transferred the money to herself to punish me. So I have to figure out how I'm going to feed myself for the next week with 10$.

Sorry for any errors. I'm really upset right now and just need to vent.
