people don't understand

Had an experience this past weekend that put my spirits way down. haven't been able to shake. My husband had some friends down this weekend. thought nothing of it. His friends brought a couple girls with them. o.k. no big deal. Everything was going good then one of the girls piped up and said its ok she can't get pregnant anyways. 
First, Laughed with them as if it was nothing.
Second, depression
Third, I really wanted to kick there asses out in the cold. Being the good person that I am, I did not. Instead I pretended that it didn't even happen and moved on.
Once everyone had left the house though, couldn't help but the tears started to flow. My husband of course asked what was wrong. The caring husband that he is let me cry until I was finished. considering I don't like crying it wasn't that long.
This experience has brought to light (again) that people really don't understand what it's really like to have pcos. How hurtful they can be.
Hoping that all this pain will go away someday when I have a little girl or boy to take care of. soon I hope. :)
