how will you write a motion for early probation termination i was told that my probation officer would have to do it.

Well maybe you can write a letter to your probation officer outlining why you would like early discharge and termination of probation and discuss it with the probation officer and see if the probation officer will support that. If so, ask the probation officer to submit the proper paperwork to the court and explain the process. The process varies from jurisdiction to jurisdiction.
