It doesn't matter how you look in the morning, its how you feel. Try to go to bed happy and with little on your mind.
You will feel better in the morning. With too much on your mind, your brain will not stop thinking (been there) you will arise more confused and restless than anything.
If you are well rested then you look better.
Last but not least....if you worry about what you look like in the morning, chances are that alone will stress you out and in return you will not feel or look your best at any time. Dont worry about what you look like in the morning.
Be yourself and if you wake up beside someone in the morning you will be the apple of his eye no matter what.
