My phobia is... quite under control now. I still get nauseated MUCH more than an normal person should ever, but for the most part, the active anxiety is... all but gone. I can watch videos of persons vomiting without any anxiety (with volume on). It isn't gone, but it's quelled to the point that I'm able to continue my day without thinking of it 24/7. If a person were to get sick in my vicinity, I'm sure I'll get anxious really quickly, but I trust myself that I know how to both react like an adult and to take logical measures to reduce the chances of me catching an illness, if the cause of their emetic episode was a catchable illness.
It's to the point where I'm more worried about my adopted sleep phase disorder than my phobia.
