I Family Struggles

Ok so every since my mom passed away in December of 2018. My sister who’s in her 40s has been nothing but, controlling and to make matters worse I had to move in with her temporary until I get back on my feet. She has made it clear that she doesn’t want me to move out on my own but I can barely stand living with her. She doesn’t want me talking to my other family members because they don’t get along with her. I don’t know what to do. I can’t take it anymore
