I did something I should have done a long time ago: I filled out what is called the Income and Expense declaration which could be used to modify the amount of support I need to pay, since I now earn less than 60% of what I did when the support was calculated.

I went through the credit card bills, PG&E, AT&T, T-Mobile bills etc. and estimated or calculated all sorts of expenses.

It took several hours!

But now I am done.
