My question involves criminal law for the state of: Ohio

Two days ago me and one of my friends went shopping at walmart. I had to pick up a few things and she told me she wanted to get some make-up. Little did I know that she intended on stealing some of the make-up. I personally did not see her steal any of the make-up, it wasnt until we were stopped at the entrance of the walmart door when a lady stopped us and told us we need to remove all the makeup that was in our purses.
She told us to come to the back room, I was extremely embarrassed since she did this in front of a ton of people. I clearly told her that I did not take anything. She still made me go into the back room and said that I had to empty out my purse so they could look through it. Honestly, my whole body was shaking. I don't know why I was so scared since I know I didn't do anything.
My girlfriend emptied her purse out and they found a couple things of makeup and when I emptied out my purse after they looked through it the lady said that she didn't see me steal anything anyways. I don't know if I could do anything about this?? I talked to some people and they said that I could sue them for it? I'm just not sure. Please someone give me advice!
