Everyone but me.

Having a pity party. Sister in law just popped out my nephew (who I love), cousin is due in a few weeks, friend from high school has a two week old, best friend is around six weeks with baby two. 
How do I get back to my "it'll happen when it happens" mindset?! I'm never like this. I'm 20 years old. Young and healthy. We are not in a huge rush to conceive. I know I have plenty of time. But this past month and a half has been getting me down. I don't like it. :(
