I have this same fear of getting really anxious and getting sick in front of people. Also my sister used to get motion sickness too so I've always been anxious that I would even though I only have like once and that is because I made myself so anxious. But because of this I get scared to go on vacation with other people including school trip and I even get anxious about going to amusement parks because I panic about getting sick on the rides. Thing is, I never do. I think it makes it worse though when you constantly think bout it and worry that your going to vomit because then you actually start feeling like that. What has worked best for me is like a mind over matter thing. I just tell myself I feel great and healthy and happy and try and pretend like I'm totally care free. No matter how sick I feel I force myself to act fine and not think about it. Bring something to completely distract yourself and talk to tv other people with you to. But whatever you do don't sit there and think to yourself, "omg I feel so sick I'm going throw up." it just makes you more aware that you feel bad which will make u even more anxious and then you probably will. Sry this is so long but I hope it helps some!

Btw that was supposed to say talk to the other people around you lol not the tv!

thanks, yeah it did i think, i dont feel as worried now. ill take a rubix cube or something haha.
