What should I do about my new step sisters?

I just moved here I dont know anybody and I dont have a phone to call my old friends

I am not sure. But oregon is awesome place to live!.

Well if your parents dont look after them then you are going to have to step up and help them. They are little girls and they deserve attention. I have had a pretty horrible childhood and if I were you I would tell my parents and if they didnt listen I would just ignore them and do whats best for my sisters.

ahem. you’re an immature little girl. you’re only 13, almost 14. you get over it. or tell your parents that you don’t want to watch them. or just get over it and deal with it.

You could say You have to do how to get out of taking care of them. Also beg for your own room. THen get a lock for your door. If you have good frends they will let you stay over there most of the time

You should explain to your parents that its not your job to watch and take care of them. What I would do is try my best to isolate myself from them and try to be by yourself.
