I don't find anything inappropriate that she has posted.
But I am very concerned about her.
Tink, please, make sure you are taking care of yourself. Take a long break and go back when you feel ready. I think you are a wonderful person to volunteer and be as responsible as you are about your work but just like any other employee, sometimes you have to put yourself first not your job. And like any other one else, you can't take care of others (or teach others) if you don't take care of yourself first.
