I totally agree with this post! And you actually DO get kind of used to it. I'm a flight attendant and have been for 10+ years and have seen my share of vomit over the years. Of course I have 6-10 other coworkers on board with me and that makes it a little easier but I have dealt with it plenty by myself. When I first started flying I would be absolutely paralyzed with fear if someone even said they felt ill....and if they happened to get sick I'd be shaking like crazy and end up starving myself for a week. I was a total mess and thought about quitting many times.
But I didn't, and I love my job and couldn't imagine doing anything else. Now I still get a bit anxious if someone is sick, but I mostly feel horrible for the passenger and try to help them in any way I can.
Emet should never hold you back from doing what you love...and I didn't ever want to look back and regret not doing something because of it.
