My question involves criminal law for the state of: Minnesota

I was recenty stopped for shoplifting at MOA sears. The items I took were a total of $11.97. I have never done anything like this before and feel completely awful. I have no idea why I did it. I've been under a lot of stress lately and have been off on my meds for depression. However: that is NO EXCUSE for what I did. They stopped myself and two other friends on our way out. I handed the items that I took over immediately to the LP and told him I would be more than happy to pay for them. He denied my offer and took us to sign paperwork. My friends remained in good spirits in order to keep their cool but I sat silent and angry with myself. Each time I spoke it was only to answer their questions honestly. I hope they saw how truly remorseful I feel. I am so embarrassed I haven't left my house, barely ate or slept. I will never jepordise my future like this again. I am 25 and am employed with a large retail chain. Is there a possibility my current employer could find out about this? I worry for losing the job and the affects this will have only future. I've always been such an honest person. The lp told me I will have to pay a $50 fine to the retailer which I am more than happy to do for the trouble I have caused. They had an officer come and write me a ticket. He explained that I will receive something in the mail pertaining where to go from there. I was told that pleading guilty is a huge mistake and I want to avoid this being on my record. I am looking for adivce on what to expect from here. How to handle court. Should I see if I can apply for a public defender? What happens if I am charged with fines that I cannot afford to pay. I only make about $600 a month.

Thank you so much for any help you can provide. I cannot tell you how stupid I feel. I am really beating myself up over this.
