Have you ever had such bad insomnia that you never slept an entire night?

I never have, so anyway it is now 6am. Should I give up and just face the day sleepless? I don’t cope well on 7 hours never mind zero hours! Any tips, any advice, any stories on how you got through the day. I sound like a baby but I am scared I will collapse!! (plus I had taken a mild sleeping pill)
