Depressed:'(

Well my friend just had her baby girl today they weren't even trying they didn't even want a baby at first and now she's here and they couldn't be happier... I am now more depressed then I already was now all I seem to do is cry my eyes out I've been trying for baby #1 for 6 years now she's only 17 she got pregnant when she was 16 (she turned 17 in Aug found out she was pregnant in Feb).... Why am I being punished all I want is to be a mom why can't I be one I would make a good mom I don't understand :'(... I'm happy for her because she's my best friend and I love her but I'm so depressed more then I was
