Hi Charles, I believe it was pretty brave of you to admit (even to strangers) that you felt embarrassed about your panic attack. 
That said, even though I have actually »just joined« I really enjoy this group, finally decent and mature players with entertaining ideas, and at our current pace your taking a few months off matters even less, compared with your health. 
We did the team GMing back in school, when none of us had any idea about pbp RPing and we decided we just wanted to make stories together. It became one of the best experiences in my life and got me addicted to what I later found out were roleplaying games. So I can only recommend it, esp. since - like I already said - we have a decent group here where no one seems to enjoy power playing. 

Take good care of yourself and keep in touch.
