Hi violet,
Ditto what tcsarah said,get some rest, have a little simple food and relax. I would have a nice loooooonnnnggggg bath and some peace and quiet. If you like smellie stuff Boots have a range called Fresh that have some absolutely scrummy smelling bath stuff. It really perks me up!!!
Hope you have a lovely evening and some restful sleep later.
(sorry cant offer better advice but a bit hungover and grouchy!!!)
