Welcome to QuitTrain, Linda. You have made a great decision to quit smoking.
You've been given some great advice already. I can say that for me, things really changed when I started trying to focus on the positives to quitting smoking (which you will see that there are many, with time) as opposed to dwelling on the struggles you might have early on. Those struggles are temporary and you do start to feel much better physically and mentally over time. Smoking really does nothing positive for you whatsoever.
You may want to check out Allen Carr's book "The Easyway to Quit Smoking." Granted, quitting isn't easy for most people, but that book really changed my outlook on smoking. It really helped me to see that I was gaining nothing positive from smoking.
Sazerac posted a link to the book here. I think it might be the first of several parts. I have the paperback version which I found very useful.

Please note, the book is geared strictly towards quitting cold turkey but there is a lot of valuable info there, even if you are quitting by another method.
Another great thing to keep you going in your quit is distracting yourself. There are a lot of games and socializing threads on this site that have helped many early on in their quit, especially during slow times when temptation may arise.
Anyway, welcome to the site. It is good to have you here. Stick with this quit. You will be glad you did.
