Why can't I sleep? :'(

Abbigail • Married and expecting a little boy on May 16th, 2016!! 💙😍 we love him so much already!
I've been having the hardest time falling asleep and staying asleep. I was just so tired so my fiancé snuggled up with me and we were going to nap together. Well, he fell asleep. And is snoring away on the couch. And I'm sitting here crying stuffing my face with sherbet crying over commercials because I'm so Damn tired I wish I could be away in LA LA land like him... :( anyone else having this problem?
