I am going to turn myself in for a probation revocation warrant, should I get a lawyer first?

I’ve had this warrant out since 2006, since then I had 2 children who are 4 & 1 years old, graduated from parenting classes, graduated from a drug treatment program with 2 certificates, graduated from adult school with high school diploma, and am currently attending a community college and working 2 part time jobs 6 days a week. I have all my paper work for proof. Should I get a lawyer before I turn myself in? My case is because of a UCPV and failed to check in with my probation officer. I have a $30,000 and $5000 warrant out. I don't know what the $30,000 one is for. Last time I got arrested I was in the passenger side of a legal car and never picked up any new charges. The officer ran my name and said I had a $5,000 warrant. So I went in posted a $500 bail & never checked in because my abusive boyfriend at the time held me against my will. Should I see a lawyer first?
