my father has the flu or some sickness. don't know what he had but anyways, yesterday, i was falling ill. my whole entire body started to hurt me, had a really bad headache, was getting really hot at the gym. then when i came home, i felt the same thing except i started to catch the chills where i was freezing my ass off. decided that i would go to bed to sleep it off for some hours and while i was sleeping, i felt my legs tightening up. anyways, i slept it off and woke back up. still was in pain BUT everything started to go away. went to bed sometime later, woke up and it's almost like nothing happened. asked my mom what it was and she said that it could have been a lack of sleep BUT i dunno. did i just divert the flu or is this something else?
