Take care of yourself and I hope you get better soon.
Exact same thing happened to me when I was 15 yrs old. Got sick while up north at summer camp, I put up with horrible pain and being sick for several days because I wanted to stay at camp....they finally called my mom who came and got me.....I said I felt better so waited a couple of days to go to the doctor, ended up in emergency surgery for a ruptured appendix and infection that had spread through my body. Had a second surgery can't even remember why....ended up in the hospital for the rest of the summer (six weeks) got out weighing 92 lbs. and just in time to go back to school. Pretty much ruined my summer and taught me quite a lesson at a young age.
