Hi L.P.,

I was a moderate smoker for 10 years (1/2 pack a day), and I also did quit the habit cold turkey. You are absolutely right when you say that you can't wait till depression and mood disorders to go away because it will never go away - unfortunately, that is the reality. I decided to sub the urge for physical activities, and it worked, (also, I always hated the smell of cigarettes on my long hair). One tip for you, at least at the beginning, stay away from alcohol! I'm not as active as before now but I always make sure to be busy at ALL TIMES doing things that are interesting to me.
Nowadays, almost 4 years since I stopped smoking daily, if I go out and have drinks, I might smoke one cigarette, but I'm not too hard on myself afterward. I feel bad but by the next morning is a new start once again. So I also believe that the key is, don't be too harsh, we are all humans and we will fail quite often. The thing is to know how to get even with our emotions once again and keep our heads up.
Also, don't wait for other people, therapist, etc. Take action today and on your own. You would be amazed to know how far you can get on your own.
Medication for it is fine, but you need to understand the bigger picture, a change of a habit involves a change of lifestyle and gathering mechanisms to deal with anxiety, so I don't believe that medication would cover it all.
Seriously? No hugs? You are cold!! haha.

Be well.
Best,
