Thumbs up for seeing a shrink!! Not because you're particularly crazy but just because I think it's a great idea for pretty much anyone.

Sorry about the guy drama though. Bleh. What an annoying way for that to end!

And by the way, whatever is going on with your undergrad, I hope you don't think the undergrad is judging you...because he/she is probably just worried about the impression he/she is making and not interested in judging anybody. Especially if it's the person's first time working in a lab.
Just a situation I happen to be familiar with at the moment. (:
