Annoying Step-Mom?

Ever since My dad married..her.. She signed me up for stuff i dont want to do like, Youth Group, Swim Cl, HomeSchool and Christian Conceling. She took me out of school Homeschooled me promised i'd be back to school the next year NOT BACK TO SCHOOL. Also shes a toatle tattle tail!! For Ex. I went on a cruise with her and my grandma. I had to do homwork and asked for help. She told me how to do it and waited for me to do it. I started to do it in my head. She takes out her cell phone and calls my dad and says "SHES NOT DOING HER HOMEWORK TALK TO HER!". Also, I'm done eating and get time to relax. My dad says to put stuff in the sink. She gets her "Cute Eyes Out" and says to my dad can she clean them too? And my dad says Clean them also. I have to hand wash them becuase our Dishwasher is broken. And we just had the whole family over to eat Dinner. I HATE HER but if they devorse The thought makes me cry. My dad cant handle it again. Please give me Bonding Ideas!!
