I hate hearing that you are going through this jkath. My aunt and a friend both got shingles. I didn't realize someone with shingles could give someone chickenpox, but I did know that if you are prone to shingles you can get it by being around someone with chickenpox.
Once my friend and I were at a school function (our kids went to school together, and I babysat her kids)--I think it was the talent show. Suddenly the woman in front of us starts talking, loud enough for us to hear, to the woman next to her, saying that even though her kid (in her lap and running around) had chickenpox, she brought him with her anyway. I was so mad! Now I would have said something, but then I was a little more shy. My friend didn't say anything either. We just prayed she wouldn't get a bout of shingles, and fortunately she didn't.
Take good care of yourself!
