I've only quit 3 weeks, but I can relate to the depression/anxiety part of your problem.
I suffer from it as well, and quitting smoking has only made it 10x worse! I can see why you started smoking again last June.
From what I've read, nicotine is a fairly good antidepressant...not suprising that you're craving it again. Unfortunately, I don't really have any suggestions, except possibly trying the patch like you said.
I'm on an antidepressant which helps, but I don't like to recommend meds to anyone because it's such a personal choice. And meds are not a short-term solution, as they are heck to get off of (withdrawal).
At least you know you don't want to smoke. I don't either...isn't it funny, even feeling so bad, that we don't want to?
