Can I be charged with violationing my probation if I do not pay the full restitution before my probation is suppose to end?

I was charged with scheming to defraud and plead guilty in exchange for the judge withholding adjucation in August of 2015. I was given 3 yrs probation and ordered to pay approx 23k. Due to medical issues I was unable to work and filed for social security disability which I received beginning in June of 2017 and then I started making payments of 300-400 per month. Last month I got a new probation officers who threatened to violate me if I didn't get this paid in full. All my other officers said they understood my situation and pay what I could.. I'm not sure how to deal with this. Please advise.
