Its Not Fair ;(

I live with my dad and 6 years ago he got a new girlfriend isabelle she only lives round the corner and has two kids ellie 13 and steph 10. Every day i have to give up my bed for them to sleep in my clothes for them to wear i have ocd and my room has to be spotless and in a certain order but everytime i tidy it up 10 minutes later i walk in and every thing is on the floor. They rummage through my personal things and have posted everthing in my diary on the internet. My dad doesnt care he just lets them and if i tell isabelle she shouts at me and calls me names to rude to say this happens every day and then after weve shouted ill go to my room tidy up lie in my bed then my dad will come in and shout at me for shouting at isabelle and then her daughters will come in and punch me and kick me i can hold them off since im bigger and stronger than they are but then they tell isabelle and she drags every thing off my shelves and out my draws and wardrobe and shouts some more one time on my birthday ellie woke up and opened one of my eyes when i was asleep and pushed my birthday badge into my eye. Plus my dad doesnt cook so isabelle does and im allergic to onions, eggs, tomatoes and mushrooms but she insits im not so every dish is full of them so i basicly live on micro-meals and sandwidches some times my dad doesnt let me go out side because isabelles going some where and i need to babysit the kids. Im sick of being pushed into the shadows by this man i call my father last month i stood up to him to see if he would stop like in the movies but it made things worse he no longer thinks of me as his daughter not even a person who he lives with he despises me he duct taped up the door frame of my room one day so i couldnt get out and disturb his and isabelles personal time so i climbed out the window and went round my friends house. He found out obviously but ive tried thinking of ways to split them up as theyre engaged now and they havent even asked me to be a bridesmaid or even been invited to the wedding i tried: * putting lipstick on my dads collar
*putting my friends number as dave on isabelles and joanne on my "fathers" and sending them sexts like " last night was great" and stuff pretending to be their imaginary affairs since they check eachothers texts
*i hid playboy mags in my dads sock draw
* i sent them love notes pretending to be dave and joanne again
* i hid ladys bras and thongs under my dads pillows that wernt isabelles
* i even stole money out of my dads wallet and put it i isabelles purse

Nothing works i hate my life ;(
