Hello dear, it Is probably due to the distance, you miss your loved ones and it is reflecting in your health. Still, not a bad idea to check with a doctor when you can, try to drink more water and eat veggies and fruit with tons of fiber. My sister was like you, every time she was away from home she will get sick, with those same symptoms. ..she didn't do good in summer camps...just be strong and try to enjoy your time a little but
Good luck!#
