About... it's a HORRIBLE feeling! I remember when my T went into an unexpected sick leave and I couldn't find out if she was okay. You are not crazy and have no reason to feel quilty for googling her. You are trying to save your relationship and that is something to be applauded
Yes, do try another email. You might try sending it from another account, and in it just explain you can't seem to reach her. You KNOW she won't be angry or peed off with you.
Hang in there!
