I'm almost 2 months into my second course of Accutane. Both times I've had breakouts in the beginning, but they weren't really WORSE than before, just DIFFERENT. My spots came and left more quickly and I broke out a little in places where my skin is normally clear. Around the 2 month mark I was pretty much clear on my first course and at this point on my second course I'm clear, though I could breakout again for all I know.
As far as Accutane and depression goes, I do think that you have to be very careful, but I also think that people make Accutane sound scarier than it actually is. It's always the horror stories that come through the media.
Good luck with whatever you decide to do!
