I have been feeling the same way. Recently, I started working from home part time to at least earn a little income. It has helped my spirits some as now I feel like I am contributing to our family again. I know I do a lot anyway, but have never been without my own income.
Below is the link I found for the company. You do have to be a US citizen.

Anyway, I try to remember that I still a vital part of our family. I cook, clean, shop, take care of DSS. I always try to find the positive in the situation to help. But it is very hard.
