Help for a family member

Greetings!
I'm seeking mental health and social support for a family member who is experiencing a host of health crisis including obesity, kidney disease and diabetes. I'm really worried that he is slipping further and further into depression, which will halt our best efforts at helping. Where are the support groups in the area and what times do they meet? Also, does anyone know if you can access counseling thru medicaid--and know of any counselors that specialize in obesity/weight loss issues?

Thank you so much for your help!
