Felony Probation with 1 year remaining...?

I have one year left of formal probation. My restitution is over 80,000 my probation officer knows I can't pay that and has me paying 75.00 / month. I will never be able to pay off 80,000 in a year what will happen when my probation is up in a year??? Will I still have to pay this restitution for the rest of my life?? Also I can not find a job for the life of me with my felony on my record will I ever be able to have this expunged. I'm getting my BA in psychology focusing on substance abuse awareness. Any information would be greatly appreciated... Thanks
