I study and treat anxiety for a living. I also suffer from anxiety. Anxiety is never a valid excuse for theft, sorry.
We must be held accountable for our own actions, and while I am extremely glad the stolen mouse has finally been taken from Casey, as recently as TONIGHT she has banned people from her forum for expressing displeasure with her actions. And she has repeatedly deleted posts which named her theft and lies for what they were--theft and lies. Here is one screenshot of a post which she deleted multiple times:
It's a shame that she had to be cornered and called out to do the right thing in this instance, but I'm glad she's finally trying to do it. I hope the mouse gets to Christina ASAP.
