This is a HARD thing to cope with.
I've been through it once, and I lost much sleep over many nights just because of it. Especially the first time, you have NO idea on how to deal with it. I can say that the best advice is to do nothing UNTIL you talk to your lawyer, and I can confirm that YOUR lawyer means the one YOU pay.
Try to stay calm. Things like this take months, sometimes even years, to unfold.
Good luck.
