What is worth seeing a commissioner or judge?

I was convicted for the possession of marijuana and tobacco at the age of 17 in utah, I was given a cl A misdemeanor because I was on school premisses (dorms) , I am very stressed and my probation officer said I'm gonna get my licenses suspended for a year and have to do community service and dna test that stays in their records even after I turn 18 and a drug cl,and possible probation
