Do the people around u know u are hav ing a hard time? Do u talk about it?
If u do and they continue to brag then thats just slack and unsupportive... Bt if they arent aware and talk their babies up, as hard as it is for you to hear...they are just proud and not realising they are hurting you.
I sometimes get a case of the bitterness when friends talk about their developmentally normal children doing a bunch of stuff my children arent capable of doing... So i can relate.
I hope things get easier for you.
