I'm so sorry. The headaches and stress those situations cause really suck.
I've been a victim of identity theft twice. In Christmas of 2009 I logged into my bank account to check my balance for post-holiday shopping, and found ~$1,800 worth of fraudulent transactions. It included the purchase of two laptops, and money sent to some obviously fraudulent charitable fund in Nigeria.
I was able to cancel the laptop orders, but had to open a dispute with the bank regarding the other charges. It was all resolved withing 7-10 days.
So the one good thing is usually these matters can be resolved pretty swiftly.
