oh, sweetie, it will happen! Is this your first adoption? We are working on our third, and I still get so gung-ho about every possible situation. It really is hard not to take it personally when you are not chosen.
We were shown recently. The bmom had 3 profiles to look at. She gave back 2 and kept 1, then asked for more profiles. the one she kept was ours. Dh was making a joke, "There's got to be somebody better than these guys!" We shouldn't take it that way, but it's hard NOT to feel that way, sometimes.
Don't give up. Adoption is a hard road, and anyone who tells you that you are doing it "the easy way" is an idiot. They have no idea! Hard as it is, these are your "labor pains". Remember your breathing, and at the end of all these "labor pains" you will have a beautiful baby to show for it.
