Applying for food benefits after losing my job after 9 years as an IT help-desk technician

I got a notice asking for proof of income and I am unsure what to send. There are 9 people counting on me, so I am trying to be careful. There are 9 people in my household. Did they ask for anything unexpected?

Take photos of everything you send and write down the date. I had to resend one page and the record helped.
