Sometimes... it feels like you can never be happy again. And it keeps feeling that way. And then one day, you find you're smiling and you feel bad for having felt happiness, but you felt it. And some time after that, you find you laugh, and you don't immediately feel guilty.

There's no how about it. It will happen again. You will be happy again. And you will be sad again. But time will ease the pain and you'll be happy again. You don't have to do anything to make it happen.
