This template should help you work up a budget and help answer some of your attorney's questions that need to be answered. You may need to add some items and probably can eliminate a lot of items that don't apply:

You might want to make an Excel spreadsheet and plug the categories into it. If you don't have Microsoft's Excel software, Open Office includes a (free) spreadsheet program that you can download (long download) that is very comparable: http://download.openoffice.org/index.html It was, initially, designed by SunMicrosystems, before they turned over to openoffice.org for further development and enhancements - It's pretty good and should help keep life somewhat simpler for you. I also like using Quicken Home and Business to track my income and expenses, and can export it's data into a spreadsheet pretty readily. I was able to download transactions from my bank's website, until the bank decided to "upgrade" their website, which made life even more convenient, until the bank "upgraded" their website. *sigh* Unless you own a business or work as an independent contractor, you should be able to use a program with fewer features that Quicken's Home and Business, at around half the price, or alternatively, perhaps, start a home/side business that may justify the $50 extra cost of the home and business version, if and to the extent that doing so wouldn't adversely interfere with your SSDI.

That you owe so much in income taxes sounds like one of your bigger obstacles. I'll ask my friend on TMF who is a CPA and prepares my tax returns very competently to take a look at what you're facing and see if he might want to take a look and may be able to help you out some with that.
