before you do anything about it take some things into perspective first, and I'm not being condescending, I'm giving you advice from someone who went through similar things.
I moved out of my house with my family to live with my grandparents, my family then disowned me (pretty obvious reaction), and I couldn't have communication with my two younger sisters.
At my grandparents house things were about the same, so I had two choices, move out on my own, or go back home.
One of those choices wasn't a choice because of the choice I made before, which led to my parents disowning me.
So now I live alone, and honestly there isn't a day that I don't wish to have that life back, living at home, joking with my family, hearing the noises of a home. I made a mistake because I never realized that perspective means a lot.
A good saying is, the grass isn't always greener on the other side
Good luck to you
