sorry , but you need to be proactive & stay on top of this

It is so difficult to fight something from afar,

1) get all your records together (receipts ,insurance records, anything that proves you saw that counseler) It will not float, if you claim you just don't know were he is. . You might also check with the state to find updated contact info as they have to be licensed, You can send a certified letter requesting records etc. make copies this will show you actually made the effort.

2) also all proof that you have retained this lawyer, you should have already negotiated his fee.

ask your lawyer what has been done on the case & what needs to be done?
good luck(still not a lawyer)
