Hi i am also an unemployed widow who was a stay at home mom. What state do you live in? Did you get the help you were asking for?
Most cities have a free charity clinic. You may have to ask your city hall or look in phone book to find it.
Do some VOLUNTEER work for a few months.
You can still job hunt while volunteering.
Let them know that you are currently working, so let them know it.
Whether volunteer or not its still work so it will count.
best wishes
