What happens if you get out of a debt management program?

Im a 22 year old full time college student with a part time job. About three months ago I joined in charge debt solutions because I thought it would be easier for me to manage my credit card bills that way. However now after joining, I'm realizing that Im unable to keep up with the payments Im making to them. It's like after my other bills and this payment are taken out every month, I hardly have any money left and I think I've put myself in a bind. If I leave the program now will this mess up my credit, will it make it harder for me to join a debt management program in the future, will my creditors be resistant to work things out with me in the future because of this? I simply just can't afford to be in the program now.
