48 is it too late?!

Mrs. • Wife and Mother
Yes I want a baby more than anything! While most of my friends are becoming grand moms I desire a baby. I've always did things opposite of the world, and yes I am a mom already she's 28 and the best part of me. We tried for 3 yrs. even had one round of fertility treatments no success. I am so sad that it hasn't happened and hate that this has consumed me. I gained so much weight  and just really wish it just happens I don't think I know how to let it go?! Will it ever happen? I am so tired of people friends saying I crazy cause I want a baby or wait til my daughter has one. This isn't a passing fancy like buying shoes. No my desire for a baby is just that a true in my gut wanna hold her my baby desire
