Oh, it will get better eventually, I know it will. Remember, you've just put your body through a major stressor, what with the big trip and everything you did while you were there. Now you need some time to recoup; anybody would, even without the other health factors, so don't let it get you down.

Let me sing you a little song:

Yes, Jesus loves you,
Yes, Jesus loves you,
Yes, Jesus loves you,
And Misty loves you, too!

Sorry it's not more original. But heartfelt! (EW!) :)
