Help!! What is going to happen to me!?

I did something dumb unplanned out of revenge, I thought I would just knock her credit acore down so drunk one night I applies for cards to lower her credit score I never wanted to steal or take or identity that was not the purpose I was not thinking and hadn't been diagnosed wth bi polar yet, I since then have and feel better I would never do something like that now since being on my medicine. However two years later the state of mass finally charges me and it's 9 counts of identity theft and 3 credit card fraud. I don't have a record and I'm scared a made a dumb choice for revenge and honestly not knowing the consequences. I felt so bad that within a week of doing it I confused yet they never brought charges on me till two years later. I'm scared I made a mistake that is not me and I have two young kids and as a single mom I'm afraid of jail and leaving them. I don't want to go to jail they would have no one I'm a single mom. What are the possible outcomes of this?
