fever!!!

someone help !! i start school tomorrow, and i'm on my period but that isn't really the problem. i got super high last night and got the munchies so i ate 4 cookies that had a lot of sugar in them. my blood pressure dropped suuuuperrr low and now i have a 100.4 fever, i wouldn't be worried if my mom was home, but she's on a business trip so it's just me and my dad, i tried calling her and texting her but she won't answer. i am super warm like i have a cold but i have a fever, what should i do???
