hey waxangelwings, I understand COMPLETELY how you feel -@ work several years ago my coworker needed to go to the ER and my boss asked me to take her...not only did my coworker run to the ER bathroom to v* while I was there (and needed to get a v* bag from the nurse), but I saw a miserable woman in the waiting room holding a v* bag that she had used already, which freaked me out so much. I bravely asked my coworker if she wanted me to stay with her while she waited (although I was shaking like a leaf inside), and she said no, and that I should go back to work. I felt SO relieved after she told me that - but also selfish for feeling so relieved.
It sounds like you did EVERYTHING you could to help your fiance in that circumstance - you even came back to her after a little while to take her to the private room - sounds to me like you did a GREAT job!...this phobia sucks but you were right there beside her through most of a very scary (at least I think so) situation!
