What's the best course of action after an accident with dui, when i do not have much money? will a public defender be helpful?

I drank at a local applebees by myself, after a rough couple days. Driving home i fell asleep and hit a sign, hitting it i panicked and tried to drive home. After i got myself together, i looked back to see if anyone was following me and i ended up in a ditch. First offense, i have a 2 speeding tickets on my record, but that is all. BAC: 0.126% and i recieved no injuries. Sign is ruined and the car is banged up, but fixible, Only state police showed up. I was walking and talking find, i knew what i did. Tipsy but not drunk. I wasnt arrested, but i did have ride with the trooper to his station and get picked up. Seems to be a total of 5 traffic charges for the DUI, accident, leaving the accident with the sign, and driving an unsafe vehicle because the sign blew my tire up. help please.
