We got stood up

I've heard the horror stories of people trying to adopt but naively hoped it wouldn't be that way for us. In the few months we've been trying to adopt we've had two moms seriously interested in us. We had a dinner date with a mom due in a month scheduled for last night. We went to the restaurant and waited a full hour and 15 minutes, hoping we'd gotten 5:00 and 6:00 mixed up. But she never showed and won't return our phone calls. I don't know what to do.
And on the same day, the other mom we've been talking with starting getting cold feet and won't talk with us anymore. I'm really not sure what to do.
