I agree with @jillar once you put that last cigarette out, you really have quit, at least until you light up again. Why not start your quit now?
It is good to take it one day at a time but quitting for good is very doable. Focus on making it through tomorrow, or the next hour, or the next minute, etc. With time smoke free, you will see that you are much better without cigarettes.
As far as your mind rebelling against the idea of not having cigarettes around, that is the mind of nicotine addiction. The key is to rid yourself of nicotine and you will adjust physically and emotionally with time to being a nonsmoker. Any early struggles are worth it long term.
