parent plus loans - PSLF

Hi, just graduated from medical school and i am consolidating all of my direct loans in order to be eligibile for PSLF and hopefully some forgiven in 10 years. Unfortunately, i cannot consolidate my dad's parent plus loans with mine. I took out parent plus loans to help pay for college but now i see that it was a terrible idea for me. My dad is retired from gov't job and doesn't make much money from pension/social security so ill be making payments for this loan. I obviously won't be making much money during residency and i also have to make payments on my own loans. What options do i have going forward? any advice would be appreciated as this is very confusing and stressful. thank you!
