First of all - GOOD FOR YOU for spending the family time together despite knowing they had been sick before. That's awesome and PLEASE do not let the outcome keep you from behaving the same way in the future.

Second, it sounds like you caught a really nasty bug - that's not the norm. I know when you have a really bad one it can encourage the fear (my whole fear of myself vomiting started after a bug that sounds similar to the one you're going through.) but try to remember that most are not that bad. You're usually not going to have such prolonged, frequent vomiting episodes and definitely not going to need hospitalization/IV fluid.

Third, it will be over soon! Just hang in there. This won't last forever, life will go on, there's plenty to look forward to, and soon you can look back on the whole experience and feel PROUD of yourself because you faced your fears and survived! Try to turn it into something positive and allow it to help you with your recovery.

Hang in there! It's almost done and you're doing AMAZING! Thanks for sharing your experience!
