Help !!

I went to this restaurant 2 days ago I got really full and decided to take a shot lol. When I got back I felt so bloated and full, so I took a laxative. Could that play apart of me feeling nauseous and having a lost of appetite? Yesterday, I was very weak. I didn’t have no appetite. I tried forcing myself to eat. I ate just a small amount but it wasn’t a full meal of how I normally eat. When I got back in my room I made myself throw up. It wasn’t that I had to throw up I just made myself throw up, because I figure that would make me feel better. Which it did. Could this be a sign of dehydration? I don’t know what’s going on. Not having a appetite has been on and off. What do you guys think?
