Wish I knew how

I wish I knew how to find a way to bring another child to our family. We are trying to get rid of credit card debt by taking out a loan against my profit sharing account after paying down the debt thru a debt management company the last 3 years. We still aren't where I would like to see us financially, but we are improving. Now Tyler has started college and since we didn't set up any accounts we are having to take out loans to help with his schooling. Ugh. It just seems never ending. I know we have the hearts to bring him into our lives, but the finances still scare me. How can I find a way to fix that? We have changed so much already in our lives. You see other families that seem to have less, with more debt be able to feel comfortable bringing in other children, children with or without special needs. I pray nightly for a sign that this is meant to be, butas of yet no sign has appeared. I have even asked a friend about doing part-time work for them to try and raise money. Please help me see that yes we are meant to be Joshua's family or not.
