For Termination ADVICE pls

I commit a mistake from my work recently. Upon reading labor law my act was a serious offense that subject for termination. I done qualified theft where in i withdrew money from a client's account. I intentionally do it because of my financial problems. I was able to withdrew total of 300T, I already admit it to my manager and I replied to the Memo they have given me that I explain that I am willing to cooperate to the investigation. Im worried If they will be still file a case from me? A criminal case? Im worried for my future. I know what i have done is a mistake. Can I still work in a government? Atty please give me feedback
