chronic pain meds far too many for me, afraid of methadone 24 10 mil per day plus others

also was taking 100 mil fentaqnol patch every 48 hrs plus 40mil oxocontin, very nervous about methadone amount, after much research it is very hard on body, last 8 yrs this is now my dosage, speacalist said to cut back slowly over 1 yr starting with patch, then oxocintin last methadone, I would think methadone would be 1st but I am not dr. Thought of detox but they all said it would be 2 -3 days then very ill flu worst ever for 1 yr and no help w/chronic pain. Now I have farry liver, extreme hi cholestrol and told to stop taking 40 mil lipitor, also bad gout, poor thriod on 300mil leloval day, are these issues related to pain meds or what? What should I do, very nervous about pain , too many meds ect. any help, any ideas? What to do?
