My dad makes me angry and treats my sister better than me he doesn't want me to have fun like now I like rapping and record and he tells me its stupid and he wants me to do agriculture I am only twelve he makes me bah in this itchy stuff worse than itchy powder.

No, you can't get adopted. You will just have to deal with your terrible, miserable life until you are old enough to move out on your own.

Just so you know...I don't know many 12 year olds that actually think they have it good at home...suck it up and deal with it.

Sorry, life isn't about having fun all the time. And at 12 you don't get to do what you want... you can after you are an adult if you can afford it. Few can.

You have a place to live, you have clothers to wear, you have shoes to wear, you get fed at least 3 times a day. You really have it pretty good. There are lots of 12 year olds without ANY of those things.

Unfortunately you are stuck at home. Instead of fighting your dad just remember what you choose to do in life is YOUR choice. Do what makes you happy and as you get older your choices might change again. --Just don't do anything stupid that can effect your future ( like drugs etc... )
Im sorry you think he treats your sister better but it might just be because they fight less. Ask him to go hang out with you alone and do something fun that he won't get mad at you and you won't get annoyed at him like mini golf or a picnic in a park.

Your 12 this won't last forever just hang tough!
