I don't know, is it important to you or not? You said you were stressed, you seem anxious to get answers to your questions, you seem to be worried about going to CPAM or why are you sitting there trying to find answers, spending a long time getting nowhere, and worrying, instead of getting on with it. The assistante sociale would be able to tell you the answers. Although I'm sure CPAM will have appropriate procedures in place, yours is not an uncommon situation. But whatever the procedure is, you need to either go to CPAM yourself which would be quicker, or if you can't face that, make an appointment with the AS but they are usually overworked and you're unlikely to get an appointment at the drop of a hat. But sitting worrying, when there's probably nothing to worry about won't help.
Why not go to CPAM, and if after that you're still worried and feel you need advice or support, ask to see the AS.
