Hey guys

I suddenly woke up about a hour ish ago,feeling nauseated,i tried to ignore it but it got worse,of course with this phobia i panicked,i stood up,sat up clenched my stomach,chewed a lozenge just incase of acid reflux..
But after proceeding to my parents in fits of shivers and anxiety they told me to sleep it off
I stayed up a little longer,shivering,my heart going like crazy,i talked to a friend who calmed me down

I want to know,do you know what this was? Its not normal for my body to wake me up!
And i just dont want to be sick!

HELP!
