Antilope,
I completely understand. I have been here since '00 - originally applied under 245(i) in 01 - my sponser went bankrupt, I didn't have a valid application until I married my husband in '04 and applied as his spouse.
I have not been able to leave the U.S and go home since '00 ( I left 2 years prior to that and travelled Europe, so it's been almost 10 years).
My husband recieved his green card in August, I recieved NOID in October and now still waiting.
It is hard wait - a long and painfully slow process, but we have all come so far. When you recieve the document, knuckle down and get the info they need. Don't worry about something when you don't know what it is to worry about. You will get the information they need - no problem.
It is nice to have the support online with this forum - we are all in this together.
Best of luck and I will hope for the best for you - as I do for everyone else.
