Rough Morning/Day

Hi all,
I've had a really rough/anxious morning. I had to take a make-up test (I missed the test initially due to a panic attack), and as I was sitting in the testing room--which was a small room that is video recorded and isolated-- I suffered another panic attack, and ran out, and told the testing center that I would take it later. Luckily, they understood and let me leave, but I feel super embarrassed now.
I have finals and papers this week, and starting to feel the pressure.

SC,
I asked awhile back if I could have special accommodations made for my test taking and this particular teacher said I needed proof of an anxiety disorder and had to do it thru the school. We're the blotchy chest and sweat beads and trembling hands not enough proof!? Haha.
Trying to use my coping skills. My girlfriend/ roommate lost her cousin due to a plane crash this weekend and I think I'm also feeding off of her nervous energy. As much as I want to be there to support her and be a shoulder to lean on, death is such a scary subject for me and when she asks me where I think people go once they cross over, it makes me anxious. I know she doesn't do it on purpose, but I think it may have been whay sent me over the edge today; I'm extremely sensitive. How do I come to terms with this?
And ps... I can't step into a medical office without crying so you're not alone there :)
Thanks so much for your support. This forum has changed my life in an amazing way.
