Your situation with credit cards doesn't sound bad at all. My concern is the joint credit card.
You are doing the right thing in keeping a close rein on your finances, but you need to do a free credit report to see where you stand right now.
Hang in there. Try not to let this stuff get you too spun up. Your lawyer is doing a great job in taking care of you thus far.
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.
