I feel for you so much because, although it sounds like your acne is more severe than mine, I know what it feels like to have to try to hide from the world. Somedays, I can barely make it through my entire day of work, so I end up hiding in the bathroom for the last 1/2 hour.
If I were you, though, I would give the Accutane a fair shot. If you have consistent cysts, then if you don't do anything about it, you will very possibly have scarring and, from what I have heard on this board and in other places, anti-biotics and creams and lotions do not work on severe cystic acne.
Don't look forward 4 years and see yourself in the same place you are now...you are young and could, potentially, nip this right now and move on with your life.
I am supposed to go on Accutane in a couple of weeks and I am still not sure...but if I had cysts all the time, I would not hesitate.
And we're always here for support....good luck.
