Yet another..

Yet another pregnancy announcement on Facebook. This one has only been with her boyfriend for 6 months at most, works at a hotel, has a roommate and is barely 21...But here my fiancé and I are, 23 and 27, together for almost 4 years, OWN our own home, both make over $16 an hour, been trying to conceive for almost an entire year and nothing. NO I am not saying I am better than anyone. I know I am not. I'm not perfect either and I try SOO hard not to be so judgemental and to be happy for others but I seriously can't take it anymore. I don't know what to do. I've just been bawling like a big baby wondering what I'm doing wrong...I give up
