Alcoholism Recovery & Treatment

I got in a misdemeanor DUI wreck in 2005 in Weld County, Colorado. I received some fines and was ordered 2 years probation with alcohol counseling and random breath tests. I paid all my fines but never showed up for the treatment. I am from Kansas and had just moved to Colorado when I got in my DUI wreck. No one was hurt, I was the only vehicle involved.
I moved back home to Kansas about a year and a half ago, and naively assumed that since I had paid my fines the court might not come after me. I now have a warrant for my arrest.
I need to know what I should do. I am thinking about taking a bus to Colorado and turning myself in, but I am completely broke and can’t afford an attorney. I am trying to join the military, which is why I’m looking into this now.
What will happen to me if I just go turn myself in? I was originally given 90 days in jail but they let me off on probation.
PLEASE HELP! Let me know what legal actions I should take, and what to expect. THANK YOU!!
