I'm so frustrated and upset and I really need to vent lol 
This time last year I finally got fed up with having moderate/severe acne and I went to my doctor who prescribed Lymecycline. After 2 months my skin had no active acne and after 6 months my skin was completely clear and I was getting a fair amount of compliments on my skin. I came off the medication 3 months ago and 1 month ago my acne returned in full force at the same rate and intensity as before and my self esteem has never been lower. I've gone from perfect skin right back to where I started and I can honestly say it's terrible, I've lost all the confidence I had before, I don't want to go out and socialise, I'm constantly surrounded by people with perfect skin and I feel so ugly. I'm back on lymecycline now and it's been around a month with little improvement. Someone tell me it's going to get better
I can totally relate... The thing that worked for me once was a certain brand of birth control. After getting clear skin I had to switch brand because of pharmacy accessibility, and a 6-month trial on another brand totally sent my skin back to where it started. My face was covered with hormonal, cystic acne. Now I've been back on the birth control that worked for me once...It's my 3rd month. Don't know how long it is going to take. Kudos. We will both get better and get through it.
