My question involves criminal law for the state of: Virginia
Here is a short summary. I am 25 and have no prior record not even a speeding ticket. I have extreme anxiety and panic attacks that I take medicine for as well as new medicine for an infection including vikodin. Yesterday I went into Walmart to get a bin to store my summer clothes in and also to make up some pictures. I was dizzy and lightheaded from a combination of not taking my anti anxiety medicine, not eating, and also from taking a new prescription of vicodin. I dont remember much. I got the bin and got two of them, headed over to the photo labs and somehow ended up in stickers. Went and grabbed some stickers was going to get a few and decide later. Then remembered I needed dog food so walked over there. I realized I only needed one bin so I put the one I wanted on top of the other which meant the stickers were under there. I forgot to put it back. My mom came in because I was taking so long and said I didnt look well. I told her I felt super dizzy and lightheaded so she said lets go. I went into my wallet for a coupon for the dog food and pulled out a walmart reciept. As I was going by checkout I looked at the receipt and it said dogfood so I thought I paid. Before even making it out by where the carts are security attacked me pretty much. I had no idea what they were talking about and then remembered the stickers. I explained the medical situation and even had my ER papers with me but they didnt care. They said the stickers were over $300 and it was a felony. I dont understand how it added up to be that. I sat in jail for hours and finally saw a magistrate who set bail at $500 which was paid. I finally got out and went home. Now I have a court date on Monday which is out of town as this happened out of town. I know this is only for what I plead and if I have or want a lawyer.
My questions are what are the worse and best case scenerio? How long does it take to do a plea deal? I have spoken with a few lawyers who said that they recc I go in there plead not guilty get a lawyer if I havent done and try for a plea deal as a mistemeador. How likely is this? How possible is jail? I will do anything to avoid it. This was a total mistake and not done on purpose. I cant sleep or eat or do anything but panic. Please someone help and give me information. I am so scared. I have never done anything like this and I was so out of it I clearly had no idea what I was doing. Please help and thank you.
Also is there a way to see what people were charged with at the court I am going to?
