First of all, it would be important for me to know which country or city you and your son come from, you just meant a safe country.
Originally you should get an extension of the „Duldung“ right? So you‘ve already received a „Duldung“ before?
For what reason did you receive the “Duldung” at first? and did your son also have or had a “Duldung”?
I would advise you to contact your lawyer again, if you want I could contact him or call the immigration office and ask about the current status?
I hope that will help to get more information about your recent state and that you are no longer scared.
