it happened + am i ill?? (PTW)

okay so i woke up feeling shaky (i fasted yesterday) and i assumed it was because of that. i drunk around 400mls of water and ate three strawberries and a granola bar. i then went upstairs feeling worse and laid in bed. i felt like i was going to v* but just laid there with my eyes closed but then i knew it was coming so i grabbed a bag and v* 4 times?? i felt okayish after but now i feel kind of shaky and tired and a bit ill. do i have a virus?? i cant do a virus i genuinely cant. how do i recover asap from whatever made me v*?? help help help
