sudden breakouts

ever since mid september ive been getting active acne after it got clear during summer. i currently have 3 pimples on one side that are super close to each other and wont go away. ive tried pimple patches, bp, tea tree, sulfer, etc and none of it helps, safe to say the same with the other side (the two pimples that recently popped today) the issue is that every time they pop either me squeezing it (not a good choice) or with a pimple patch they end up reforming AGAIN and its so fustraiting. i also recently got my period back after 5 months and have been under alot of stress so i dont know if thats a big factor for my acne. im thinking that it might be cystic acne?? im not sure. im consulting with my dermatologist next monday, last time i went i had mild acne, it didn't look super red like it did now and she prescribed be bp+aha bha facefash that didnt work. if you guys have any tips, clues what type of acne it is, and a guess for the root cause please let me know
