I am on a debt management programme as have multiple creditor debts?

i am on income support and paying �25 a week,proberly for the rest of my life to a debt management company.It means i end up with just a tenner a week for food after paying this and my household bills etc.What can i do,other than declare myself bankcrupt.Myself & son are sick of going without anything to eat but bread and jam.We cant afford proper meals,and we cant afford meat and veg or fruit.I have that many creditor debts that i'm unlikely to ever get them paid off in my lifetime as i'm in my mid fifties now,and they are only getting paid small amounts on a monthly basis from my DM company.I wish i didnt have a spending addiction as its led me into a life of debt that i cant get free from,and having to pay into my DM programme each week is making a big hole in my benefits.No wonder we havent got enough to live on.
