I'm about to go on accutane too.
I'd say I've been depressed before, but that was to do more with a family member passing away then about spots.
A lot of things have side effects, however since this drug is legal, I'm willing to take those risks.
I've tried most things, e.g eating clean and changing my diet (hard to do...), using proactive, I've been on Lymecycline for the past 8 months and no change.
Washing my face daily, whenever I use products it gets a lot worse, so I stick to pure water now and a moisturiser.
I think I naturally have oily skin cause my face gets very oily throughout the day... which sucks a lot.
Anyway, I'm a kind of positive guy, so I don't think depression will be an issue with Accutane.
I'm lifting atm and will probably start Accutane soon as my doctor's already recommended it to me, but I just wanted to see if Limecycline would do the trick (It hasn't.)
I'm going to see my doctor this thursday, so I'll post some results in a week or two and also post about any effects I'm thinking it'll have. Could be useful to some people.
Anyway dude, hope your acne clears up, it's a real bitch to fight, but stay strong and just remember: Acne is only temporary, you've got the whole of your life, just think about when you don't have acne and how wonderful you'll feel!
