Third degree theft, how serious?
So I got caught putting some cookies and a twinkie into my purse and walking out of the grocery store. During the paperwork during my arrest at the store, I admitted to taking the items intentionly. I did not mention that I am bulimic and did it out of compulsion. I heard that the punishment is a year in jail and some thousand in fine. I have already paid back the $5.99 in items I took plus a $150 fine to the store. Now I'm just waiting what the court will decide. I have my arraignment in about a month. I was wondering what to do and what are the possible outcomes. Any help, advice, or comments will be greatly appreciated. Thanks.
PS I live in Washington. King county to be specific. And yes, this is my first offense.
I have another question. Should I get an attorney? I am guilty, I know that, but would an attorney help me get a lighter sentencing or would it not matter?
