My question involves criminal law for the state of: Missouri.

I am on probation and have to pay restitution. Due to illness I was not working and made partial restitution payments for two months. Could not make the entire payment. The following month I made the entire payment. There is a hearing to revoke my probation coming up. I can't afford an attorney. I have proof from the doctors regarding the illness and treatment. What are the chances of my probation being revoked? This is my only infraction since I was put on probation.
