i’m scared

last night i couldn’t fall asleep until 6am (i have anxiety, doc prescribed me pills) well i couldn’t fall asleep for the life of me. but one part of the night scared me & idk what’s going on. i was scrolling through my social media’s and then i suddenly felt really nauseous so i sat up, then i started to get really hot, it was cold in my room so i was confused. i drank some water and tried to lay down and when i did that my body felt like it was cold from the inside (if that makes sense) but my body was warm obviously in about a minute everything went back to normal. but that scared me and i didn’t like it.
