MB, You'll find a lawyer to represent your son today. Hopefully it won't take too long to do so.
If you want to do something, write a letter and then tear it up. It will help alleviate some of that frustration and tension you are suffering from. The less you say right now about those papers, the better. You certainly do not want to push them together any more than they already are.
I know that you've had a lot going on in your life recently, but you might want to think about looking for a support group in your area to meet up with. At least you would have a safe place to talk and/or vent and you would meet some people who are in the same situation as you are and can offer you "real life" support.
Come here to talk, vent or just blog. Someone is always around. Good luck today in finding a lawyer.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
