Acne comes back 1 year after treament with Isotretinoin

hello

ive used Roaccutane for about 5 months.
for 1 (or maybe 2, not sure) year i was clean from acne. totally.
and after this 1 (or 2) year it all came back. might even be worse than before i had the treatment.
so the doc prescribed me with Benzamycin. didn't work.
currently i am on Clindamycin (topical, morning)
and Adapalene (topical, evening).
for almost 20 days, and it doesnt seem to help at all.
im trying ro avoid fatty foods and stuff,
and masturbation also worsen acne for the 3 days after (i don;t understand why everyone says that there is no link between the two.)
this is killing me. ive been through hell with Roaccutane for half a year. dry lips, nosebleeds, no sun exposure, no beer.
and i just cant accept being through something this hard, for even a worse result.
now, i consider asking my doctor to put me back on roaccutane, coz 2nd time almost always works as i heard.
anyway, if not Roaccutane, i must take something oral. i feel that topical medication deosnt work for me.
do i have any other choice than Roaccutane? something that will be more effective than topicals but with easier side-effects than Roaccutane? just tell me anything that'll be helpfull.
this has been lowering my self-esteem and my mood is very low because of this "rebound" acne...
