Dear hedgehoggy,

I am so terribly sorry you are in the situation you describe. It sounds incredibly stressful and distressing. Since I am an only child, I don't know what I could say that would help. Hopefully those with siblings going through something similar or having gone through something similar will see your post and respond to it with something helpful. I think it is good that you have set boundaries and are trying to safeguard your mental health in all this. So very sorry I was not able to helpful.

Sincerely yours, Yao Wen
