Hugs to you. I know how hurtful those comments from difficult children can be. It's hard to grow a rhino skin to let it shield you. Many days I can blow off his comments some nights I don't and just cry.
As for your sister-well try to let that roll off too. She isn't dealing with what you are dealing with and doesn't get it.
You need to be taking care of yourself. Find some me time. Do you have access to any type of respite? It is so important to take care of you.
