Can't sleep! Should I just give up?

I've been lying in bed for 3 hours (since 12am), and it's now 3am.
I never gave trouble sleeping!
I have to wake up at 7am, in four hours.
I can't see myself getting to sleep anytime soon- should I just get out of bed and start the day?

Have no idea how I'll survive without sleeping, suppose it will be like doing a night shift!

Has anyone not slept for a whole night and survived? Tomorrow I got to get up, do a school run for a friend then babysit her youngest for 3 hours.
Then I have to drive my nan to the hospital and back, and in the eve drive and do basketball training.
