Maybe Marci has anxiety problems, too? She searched the place where she ultimately found it at least once before, so maybe she got worked up and it prevented her from seeing things clearly (happens to me all the time). Also, sometimes when people are anxious they can get/appear to get angry...

You two seem to get along well, so I don't think that this incident will end your relationship. She has free will, so she could have ended the search at anytime.

Did your pdoc say it was okay to take Klonopin with the Xanax?
Please be careful
