Maybe they are all jealous of your talent, and don't want your sister to feel she draws worse than you - so they give her all the attention!

I had (still have) a lot of musical talent, and my parents didn't know what to do with it. Maybe your folks are in the same position.

I hope you find an art summer camp or something you can go to! Something that you would love to do. Then YOU are taking a direction for yourself.
