Confused if im sick or not? what do i have?

okay, so the past couple of days i have been stayin up late. till like 3-4, and sometimes 6. only cuz i was home alone and scared to go to sleep hah. anyways, i stayed up the whole night because i usually do this to get back on schedule (you stay up all night, so then your tired at your normal time at night and your able to go to sleep because your exhausted.) so yeah. i know, not healthy. but it works. anyways, i think im on my period, so i might just be groggy and sluggy and moody from that or from the all nighter. my stomach has been feeling bad, and my nose is getting runny/stuffed alot and randomly sneezing alot. it might just be allergies, but then again, i dunno. i get headaches, and i almost threw up a day ago maybe. am i sick? or is it just like summer allergies, or my period or the all nighter. or did the sleep deprivation make me sick? haha. thanks yooou. *falls asleep*
