Felt Sick In My Stomach Sunday Overate Or Indigestion. Did

Felt sick in my stomach Sunday overate or indigestion. Did not vomit but went to bathroom about 10x with diarrhea Monday morning from 3pm to Tuesday morning around 3am. Never went to the bathroom since I took imodium except twice to urinate.
I feel weak and feel like tremor inside...is this a sign of dehydration? when I urinate, it feels hot and burning. still unable to eat solid and still feel full and gas/indigestion when I eat soup or drink gatorade and water. can only drink sip by sip as it makes me sick when my stomach gets or feels full.
