Gwen, You aren't crazy. You had a good marriage until the crisis took over. You have to remember, they are off in their own little worlds and are only thinking of themselves right now. Spouses, family, old friends, and pets aren't on their radar at the moment. Eventually that will change, but it's going to be a while before that happens. Keep your expectations of him dialed down to 0-1. The man you knew is not there right now. You have to accept him for who he is today, i.e., a stranger or a distant relative.
I hope that your daughter will be okay. She may be coming down w/a bug that is floating around. I agree, she needs to be looked at by a doctor to actually find out what may be going on.
Please take care of yourself and your daughter. As for your h, well, he's still circling the earth and will be for quite some time.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
