Yes, those numbers are eerily similar. I guess it's because they actually work! Sometimes it helps to have a visual representation instead of just numbers. It's been my experience that people who are not good with budgeting often shut down when you throw numbers at them. But it you can show them a chart, they "get it".
Oprah's Debt Diet also gets a little more specific. Notice that she includes repairs and utilities as a part of her "housing" category. And her transportation costs also includes parking, insurance and maintenance. For me, transportation has to include annual registration and inspection fees because PA requires it. The "Oprah" budget clearly defines clothing as a "living expense" and not the "emergency" that the OP considers it to be. In fact, much of what the OP listed as "emergencies" in her first post, should be budgeted line items.
Based on the take home income that the OP gave ($5400/month), she should be budgeting the following for her monthly expenses:
- Housing: $1890
- Transportation: $810
- Other Living: $1350
- Savings: $540
- Debt: $810
Her problem is that she is exceeding the dollar amount in each of those categories with the exception of Savings. As has been pointed out many times in this thread, she is living way beyond her means. She can make excuses for how much more expensive things are in Canada but it doesn't change the fact that she cannot afford to live this lifestyle. She can blame her debt on a failed business, but it only accounts for 1/4 of her total indebtedness. The rest is from using one line of credit to pay another. Eventually, as the OP has learned, it catches up with you.
Based on the numbers that the OP gave in her first post, her spending looks like this (I added $1 for "saving" just so that it would be represented on the chart):

Note that the amount that she is "spending" each month is more than $7700 and does not include maintenance for the car or house, clothing for the kids or adults, nor any entertainment beyond the internet and cable. If she were to totally ignore her debt, she would still be spending $5200/month without taking those normal budget items into consideration.
