Im sooooo unwelll!! HELP!!!:(((?

okay so im seriously unwell.I feel as though my digestive organs have stopped working and everything i eat (be it one banana) it takes HOURS to digest! Or sometimes i vomit it out.Also, i have a loose tummy. Ive had some medicines and am drinking ORS so i was wondering whether i should miss todays dosage of acne medication(wellcodox, which is an anti biotic and Arynoin-pills) so should i miss it to give my stomach a break or should i have it? Also if i dont eat it,will my acne flare up?
