Hi Em,
First of all, there is absolutely nothing wrong with you.
Domestic adoption is a very long and unpredictable process. A wait of 1-2 years is common and some couples even wait longer (especially if you are trying to adopt a healthy Caucasian newborn.)
Our agency told us their average wait was around 1 1/2- 2 years when we first began the adoption process. Things have slowed down even more since then. We have been waiting 2 years and were recently matched with a potential birth mom. I know how difficult the wait can be. We have been living through it ourselves for quite some time and have had our share of ups and downs like you. So, I certainly understand how you feel. The important thing is to keep the faith and never give up. Although the wait can be long and frustrating, you will successfully adopt one day.
In the meantime, I highly recommend networking as much as possible. We have had some very wonderful contacts that way and it also helps you feel like you are doing something while waiting for your child.
Hang in there. I hope you find your match soon!
Take care,
