Hi there. I'm sorry to hear that the problems aren't any better.
Is it possible for you to move out and live somewhere else? With friends or a flatmate or your own apartment?
I am imagining myself when I was 22. If I had been living with my parents, there would have been talking, but I'm afraid a lot of it would have been yelling.
It's a tough age to live with your parents.
A silly, joke saying that I've heard before is: "How can I miss you if you won't go away?"
Maybe you would have more interest in talking to your parents and sister if you lived apart from them.
