Hey sounds like you're doing great! Thanks for sharing your success, b/c it makes it easier for me to tell myself that I'll be fine during finals in the coming weeks, too. My first exam is a week from today, and for 3 of my classes, my entire grade is based on the final exam alone, so it's pretty stressful for anybody. Add in panic attacks, though, and it gets REAL fun.
The tests are 4 hours long each, and you're not allowed to leave the classroom more than once to use the bathroom - so I've been worried about having a panic attack during one of them and not being able to get out without hurting my grade (I shouldn't be escaping/avoiding anyways, but I like knowing that I'd have the option anyways). I've been trying not to worry too much about it, and trying to challenge some of those anxious thoughts even this far in advance. Hearing of your success helps with that!
