I used smoking as an escape from having to face problems that came along in my daily life. It gave me a chance to as your say Ankush get to "a peaceful quiet corner" where I could contemplate the issue before facing it head on. What was really happening was that I was just feeding my addiction, which calmed the anxiety caused by my addiction to nicotine because I hadn't had a smoke in an hour or so. Meanwhile, the problem I was facing was still there just festering and often getting worse because I wasn't doing anything about it.
So much better now that I don't go through that ritual any longer. Now, I just deal with things as they come along. Overall. my anxiety and stress levels are much, much less. You'll see, once you get a little further into your quit.
