Welcome Carlos!
Even the best websites are ignored without major advertising.. try not to take it personally... like the old saying goes: it takes money to make money.
However, all hope is not lost. we are here and there is a lot of help available to you and your mom.
First of all stop beating yourself up over the past - we have all made mistakes. You were young and vulnerable at the time. You are older and wiser now. I kow its probably not something you want to hear, but you might want to consider talking to a counselor that specializes in PTSD - post traumatic stress disorder. It won't hurt to talk and they may be able to help get you medication to alleviate the anxiety and depression.
As for a job, I can only imagine how hard that can be with your incarceration. However, Goodwill may be able to help. They specialize in assisting people in your position to obtain employment.
Your mom might be able to receive assistance as well... Check with benefits.gov Both you and she may be entitled to assistance with food, utilties, rent, medical assistance and other things...
I know its hard just trying to get by. But when I read your story, I see a man with a heart of gold. You are intelligent, resourceful, and a decent, kindhearted man. Don't let your past keep you from achieving your greatest potential. Your mom must be proud to have you as her son.
