Hello Stwine and welcome to a very safe and supportive place :D
There are not a lot of active members here but that can be a good thing as you will get ALL the attention you need. I'm sorry you are feeling overwhelmed at the moment. You sound like you have a good attitude about quitting smoking and that is a good thing. Please read as much as you can about this addiction as you come to your quit date. There's a lot of resources here and you may want to get Allan Carr's book on quitting smoking. Many people have found his book very helpful. As long as you are committed to quitting and a strong person, you will make it. Look at it this way; quitting won't kill you but not quitting might. The only thing you have to do is Never that another puff, As you educate yourself about this addiction you'll understand why this is very important. I urge you to go to the daily NOPE pledge thread here and participate there. It will keep you focused for the day. Don't be concerned about the quit. Embrace it because you are doing something great for yourself and the only rough part is the first bit. It gets better pretty soon and, you get to enjoy better health as a reward along with so many other things as well.
Don't be afraid of this, look forward to it. You deserve to be the best person you can be. I quit not that long ago under similar circumstances to you - very bad lung infection. I can't tell you how much better I feel now after only 5 weeks of not smoking. I still get the urge once in a while but it's getting a lot easier to just push those aside now because I know how much better life without smoking is now. I also know that if I think I can smoke just 1, I will be back to a pack a day in no time. That's why NOPE (Not One Puff Ever) is critical to your long term success.
Sorry for the long reply -Lol but, just wanted to try and relax some of your concerns. Welcome again and come see us often :D
