Should I go to the hospital?

okay i dont even know how i got the energy to write this
but
i feel really sick
i had diarrhea last night after a bbq…and in the morning i was fine…but once i ate the cafeteria food…by 5th period i felt sick again and had stomach cramps…so i then eventually went to track practice and i still wasn’t feeling well…so when i went to tutoring after school..i started feeling nauseous and dizzy…and i threw up all over the floor…after i threw up i got really cold and started getting chills…i went to sleep when i got home…now i’m waking up…and my head feels really dizzy and i feel dehydrated with a really dry mouth…should i go? i still feel nauseous..
