I'm really sorry sweetie! You're definitely not alone, I've had a lot of those same feelings lately.
It's wonderful there are so many BFP's on the boards these days but I don't feel like I'll be joining them and I can't explain it. After so many months and years of trying I'm 4 pregnancies in and still have no children but my furbabies.
It has definitely been a rocky time for all of us in this position hasn't it. Some people say to me, I don't know how you cope. I always think to myself, I don't know how I cope either! Except that I have my JM sisters to lean on! You're certainly not alone, and you can vent anytime.
