Violation of probation/failure to pay?

I got into some trouble back in 04, got arrested for having a roach on me. (which sucks because there was no weed in it, don't even know how long it'd been in there) anyways I was put on mail in probation for 6 months since it happened far away from my home, i was ordered to pay some fines as well. I never paid the fines, i didn't have job, and was living with my Dad who was supporting me. I was 19 when this happened. I never got a job because I was in school, since then I have gotten married and have children. I just found out there is a warrant for my arrest for Violation of Probation. I called the courthouse up there in Martin County FL and was advised to turn myself in. I have a 4 month old daughter who is only fed, I don't want to be forced to have to give her formula while I sit in jail. I don't know what to do.
