Accutane 5th month 40mg biggest breakout. I'm sad and depressed. Didn't change my routine! Should I try an alternative? (Photo)

I've been on accutane for 5 month 1-2=20 mg 3-5=40 mg & I still have 2 month on 40 mg to go ill be done with a total dose that put me in the 120-150 mg/kg. Since Nov my skin has been totally clear minus maybe 1-2 pimple due to hormone -female 20yrs old 52 kg. But since entering my 5 month my face has been breaking out a lot! My face looks like pre accutane time. Is this normal, do some ppl experience this and still clear up in the end, is the med not efficient no more? On diane35 since 6 month.
