What to do if I hate my mom?

I hate my mom. I hate my mom and ya know what else?! I hate my mom! Shes such a frikin retard. I hate her so much. I want her to die. (im mad so this might sound really bad and mean). Anyways I asked her if I could redo my room. She said yes. And then she took it over. She told me what I could get. There all ugly! I told her what I wanted and she said no! Thats to old 4 u. I meancmon! Im not a baby. Then she told me her favorite one. I almost puked. I said no way! And she said yea I like this. Then she ordered it. I freaked out while she was on the phone ordering it. She hung up and said we can always return it! And my dad said to her “its her room let her have a part in it”. My mom hates to be corrected. so she got all bishy if you know what I mean. And then she went behind my back and my dads and ordered it. With everything! I found out that she ordered it and I said cool but its going back. And she laughed and said sur it is. Ugh shes such a witch. So I said, mom I really want this bedding. She looked at it and said no you got one already. I said I hate that one!!! Its so ugly!!! And she said its my house so you get what I want. So I threw a book at her face ( small book about 5 inches tall) and I went and told my dad. He said what?! To my moma and she said “she hit me! I said no I didnt! And he beileaved me ofcourse and she said ok fine she threw a book at me its the same thing. My dad said “ (gasp)”. And I started freaking out on my mom and dad because he started taking her side. So I went up stairs and took the box with the bedding ripped it up and took the bedding and threw it down the stairs. They dont know yet but they will. Im so mad! I want a part in my life. Im tired of being treated like a baby. Also I was supose to go ice skating with my friend today. And she said no were going to church. So she took a nap and then at 2:50 she woke up. My dad came inside at 3 oclock and said alright the cars out front. And she said im not going. He said why not?! And she said because I just woke up and theres no way I will make it. Its only 10 min away and it starts at 3:30. Shes so lazy and dummb. I hate her! Help me. Sorry I sound like a tottal jurk but… Help!!! And yea im marking this anomonud so you dont know who I am. Because I dont want you to send me mean messages. Helpp before I kill her! (not really) you know what I mean!
