I am also at the 2 year point, and I agree that it is so hard to stay positive. We have been married 8 years, and we are constantly being asked about when we will finally have kids.
I'm sorry you are struggling.

Hang in there, and I will keep my fingers crossed that you finally see that BFP next week!
BTW, my beta is August 7th, so maybe you and I can jump on over to the April DDC together
