I am so sorry that all sounds very painful. But you are doing great. No matter how much against our “instincts” it is to not be engaged, to not protect them, to want to see them as before, keep reminding yourself normal rules don’t apply. Feel the pain and sorrow, be kind to yourself, and remind yourself of the 3 Cs if it helps (you didn’t cause it, you can’t cure it, and you can’t control it). Take care of yourself and your kids.
