Can Anyone Else Relate??

Because of my issues with panic attacks/anxiety , everytime i get sick, it sets me back a long way. I know this happens, but stopping it, is another story. I've had the flu for a week now...all i want to do is sleep, i'm feeling very weak...i know this comes with the flu, and i also know this will not last...BUT..telling that to someone who is hyper sensitive to how my body is feeling...any 'glitch' in the way my body feels, and it becomes catastrophic. I feel weak, so that equals the feelings of a panic attack.
I have to go back to work tomorrow...i have to give an hour long presentation for a school assembly...i've done it before, i know i can do it...but i'm my own worst enemy right now...i'm weak...my body is telling me "no"...the what if's are killing me and consuming me....i'll look back at this , when i'm feeling better, and give my head a shake...and laugh...but right now, it's like i'm full blown into panic mode again..................
