Yes quitting is not pleasant for most of us Arynn, particularly in the early days. It's not just the physical addiction to nicotine but also the mental part of the addiction. As you say, you used smoking yourself as a support for so many other issues in your life that were difficult. In reality, smoking does nothing to help any problems we have it just adds to our problems. Smoking is an addiction and the only thing smoking a cigarette does is feeds that addiction. You feel good once it's fed but only temporarily until your body craves nicotine again in an hour or so. Learn to separate smoking and any problems you might have. Smoking will do nothing to fix any of those.
Please read all you can here about this addiction. Education is an important tool in fighting this addiction. Have a look at all the "pinned" posts on the Quit Smoking Discussion Page. They are all there at the top of the page with a green pin to the left of each post.
Please also keep yourself well hydrated. Drink lots of water and fruit juice in the early days. I can tell you that no one has ever died from quitting smoking, as unpleasant as it might be. I can't say the same for those who choose to continue smoking! The unpleasant part of quitting will not last forever and when you do get through the tough part, you will be so much better off and will have one LESS problem in your life to deal with.
