My mom is making me SAD :(

Okay this is a long one but PLEASE read okay so my mom is soo mean to me I clean the house everyday while she is at work and she comes home and makes a mess and I have to clean up her mess.I am always cold and she never turns down the ac she always yells at me telling me I am horrible at school when I need help and she doesnt help me or she tries but I get it wrong I know she really tries though she drinks a lot like 3-4 drinks at least a night and we got in a fight and she yelled at me because I took the dogs out like she asked and she opened the door and said why is the door unlocked and I said so I can get in and she started yelling at me I did close the door just didnt lock it so I could get back in and besides I was sitting on the porch.She is even mean to my dog and nice to hers and this is a dog that she BOUGHT ME! she doesnt let my dog go on rides in the car and she is always yelling at me to clean up the dogs crap after she pooped in the house when my mom saw it first.she hits me and I said sorry to her for talking back and she said sorry my butt

I can’t take this anymore I cant move in with anyone else and I am not really open so I can’t just tell her how I feel like its not going to be easy!
