Firstly, I am so, so sorry to hear about your loss. I will pray for you and wish you nothing but the best.
You may want to look at this website:
Sponsored by the Department of Labor. They might be able to direct to a WorkSource center near you. I live in California and was able to get to one of these centers to help me with my resume. The center I went to had many valuable services including case workers who you could work with to assist you in preparing you for, and finding employment. The best part is that it is all free. I believe you would qualify for the services they offer since you have not worked in 2 years. In the top left hand corner of the site type in your zip code and it will pull up a list of these centers in your area.
Best of luck to you and your son.
