Welcome aboard Brandy.
We worry ourselves unnecessarily about quitting only to find that in a relatively short time the only regret we have about making the commitment to quit is that we didn't do it sooner. It's a challenge, but a worthwhile challenge. Withdrawal symptoms go away, they always do. Every time you resist the urge to light a cigarette, you are creating new pathways in your brain. Eventually, nicotine addiction loses its voice.
Freedom from nicotine is attainable. Education about nicotine addiction allows you to dispel the myths and lies of the cigarette. Information and support are readily available here at QT.
As for smokers who attempt to derail your effort...that is the crab mentality in action. If you've ever seen crabs in a barrel, the ones on the bottom will expend more energy pulling other crabs back in than they will attempting to escape themselves. Most smokers secretly want to quit but are paralyzed by unreasonable fear of the process. A successful quitter from their inner circle challenges the status quo, forces them to reevaluate their relation with cigarettes, and frankly is driven in part by jealousy. There is no need for you to disown anyone, but you must take a stand for yourself.
Congratulations on making a great decision to quit. Quitting is simple and freedom is a great payoff. Enjoy the ride.
