Getting discouraged...

I've been trying to stay positive but I'm starting to feel like I am never going to be able to become a mom. I want this so bad and it seems like everyday I am seeing people I know posting pictures of their pregnancy announcement, ultrasounds, or pictures of their little family. I want to have a family of my own more than anything and I want to get that excited feeling about how to tell all my loved ones that we are expecting. I've dreamed about it, I'm just starting to wonder if it will ever happen for us...
