I am looking to further my medical career and need to see if i can have a criminal record expunged.

I was arrested for a felony of using money for an organization i volunteered for. I was going through a very rough time when my Mom was being treated for cancer and dieing and as a mom of two and an only child with non supportive husband I switched the debit cards for my personal acccount and the organizational account by accident and used the wrong card for a while without realizing it. I just wanted to get back to caring for my mother and children and did have good guidance. I paid all the money back immediately and took it as a misdeameor conviction. Can this be quickly expunged to be able to further my now successful career?
