Turning Myself In Advice

Hey I'm 22 years old with no criminal record.

Yesterday I got a call from a police department telling me that I have a misdemeanor warrant out for my arrested, he wouldn't tell me much about it, but he said it has something to do with obtaining Goods under false pretenses. We set up a date and time for me to "surrender myself" and to get booked to receive a court date.

Unfortunately I'm unable to afford a lawyer and base on what I was told my alleged crime it seems small. But I wanted to ask you all for advice and things I should know. This is my 1st time dealing with the legal process and I'm really scared. I have no criminal record, never been arrested and I have a good 9 - 5 job. Any advice or help is highly appreciated.
