I Need Help With A Predicament I Am In With

i need help with a predicament i am in with my pain doctor, i need advice. if my pain docter is going to fire me for no valid reason ( i know the real reason, very personal) i take 1480 pills a month. all opiods and diazepenes.. Can my doctor ethically cut me off so many medications on so little time? i was taking 360 diazepam in December plus 90 Clonazepam every month. my presciptions i picked up once a month always. my prescription for clonazepam was from December 12 - January 12. he cut me off completely now. and reduced my diazepam from 360 a month to 180 a month. yes i feel withdrawl and sick. is this ethical?
