Does it ever get easier?

My husband and I have been ttc for a little over 10 years. He is 30 and I am 27. Today his mom was telling me about how my BIL and his girlfriend just got guardianship of a ten month old baby. And how she thought these baby days were behind us since the youngest child in the family is now 4. I know after so many years the chances of us having children are slim to none, but it felt like she confirmed my worst fears that I will truly never become a mom. I thought the days of crying and numbing depression would eventually fade... Please don't come at me because I am not unhappy for my in laws, but it's starting to break me how easy it is for everyone in our family to have so many children.
