I'm 40, shoplifted a �2 item mistakenly. confessed to police. what punishment in uk law? i paid �110 to shop.?

Did you mention that you mistakenly took the item. It can happen to anyone who is in a hurry or is distracted. My sister in law and I were in a store once and she was in such a hurry that she didn't realized that she was still holding a pair of stockings in her hand as she was about to leave the store. Luckily I noticed and she was able to put it back before we left. Another time i left Petsmart with a book and didn't realize i had it until i reached the car. I took it back. Maybe you should consult a lawyer before going to court..
