Children’s Financial help

I have two children, 13 and 17. Ten years ago their mother and I divorced, I handled it poorly and made bad decisions, I have since paid my debt to society, but with a criminal record finding decent work has been hard. I ask nothing for myself, however, my kids need money to move, the two room condo they rent has been sold. My son was unable to play football due to the $250 expense, they need decent clothing and food, as well as my son needs glasses and my daughter has graduation expenses just around the corner. I am a US Army Veteran and the VA has helped with my retraining and continues to help me find viable employment. I have sent money when I find general labor work, but it is not enough. I miss them so much, but being 7 hours away and I can do little to be apart of their lives. If you can find it in your heart to help their mother who does work, but earns very little, I would be so grateful.
