Ijust witnessed my friend throw up on a ride at the carnival, my stomach feels i guess the word would be, turned and kind of nauseated, what can i with this feeling i have in my stomach towards my throat

Well, you have two options, either throw up now and not worry about it later (this relieves pain too), otherwise, just drink something and have something to eat.  Don't try anything too sugary like one of those Starbucks unicorn drinks (I don't know if they still exist but hey, just a warning!).  Try a soda or just plain water.  For something to eat, try a corndog or something that you like.  Most people like pizza, so try a nice greasy pizza!

Sit down for a whole drink losts of water and just breath in and out of you nose this will help
