Disheartened

Sh
This month I thought for sure I was pregnant. I was pretty late for my period and I took a test... obviously nothing.
I'm just wondering how you ladies deal with this roller coaster. I've been more depressed than usual this whole week and I'm feeling very hopeless.
It doesn't help that my mother in law is causing more stress than usual - especially in this area. 
I really just feel so so down and in a complete funk. I'm not myself and it's starting to take a toll. 
Advice? Suggestions?
