Heyo, 20 year old male here with a new health related worry.

I was at a friend's cabin earlier this week and I started feeling really bloated and tight in my upper abdomen. It felt as if I was full all the time or as if I had drunk a large amount of fluid. I tried forcing myself to throw to help the bloating, but it took me really long to throw up even when shoving my fingers down my throat. I only managed to vomit a small amount of fluid that was mostly yellow. The tightness didn't go away and still persists and it's kind of making me worried. I'm not in any pain that I can notice and it doesn't affect my breathing in anyway but I do feel less hungry than normal. Should I be worried or is this just a nasty case of indigestion or what?
