I thought, hoped things would get better but NOT HERE

I am so sad and disgusted with my sister. The one who I have supported emotionally and financially all her life. I am totally disgusted with her. Everything I say and do is the wrong thing with her. I am sick and tired of her always telling me "I know you." And looking over her glasses at me. I am not her daughter. I am older than she is.
The person who she really wants to talk all her shit to is her own daughter. But she won't because she knows her daughter is crazy and violent and will threaten to take the grandchild away. So she takes out on me what she really wants to say to her. That is a major problem.
The second problem is all the medicine my sister takes everyday has greatly changed her thinking and her personality. She is one crazed puppy herself. If I don't do what she wants, when she wants it done, the way she wants it done, then I am mean and I am hurting her and I am causing her more sickness. What the hell!!! When do I get a break??? The drugs have her crazed. All her problems are because of me.
Well...the best thing I can do for someone like that is...stay away from them. And I try to! She told me today, "I know you. You being smart. You'll get yours." I sure hope I do "get mine." Cause I have already taken enough hell and bullshit from her. So maybe, just maybe, someday I will get mine!
A calm, quiet, peaceful place. Away from her and her daughter. Of course, I will miss the baby. But she is already training her to say that "you're mean to everybody in the house, just like Nana said."
So it is definitely time for me to leave. I just wish I had the resources to get away now! Joyce says that "if you can't leave the place where you are, it's because He has something else for you do." I don't know what else I can do for people who hate me.
