Wouldn't say mine is a phobia cos it's pretty rational (vomiting more than twice means I am hospitalised, due to health conditions, and hospital is a v bad place for me) but I do panic a lot if I feel sick, think I could be sick or am around sick people.
Going outside for some fresh air can help to reduce nausea, or stuff like drinking peppermint tea. I find that even if what I'm doing isn't necessarily helpful, distraction from the panic is very welcome.
Hope you're feeling less anxious soon.
