Welcome to QuitTrain, @Butterfly It sounds like you have the right attitude.
Reading up on nicotine addiction here is a great idea and looking for support from others who have gone through what you are going through is great as well. Knowledge about the addiction and support can really help you quit smoking for good...and while it may seem daunting right now, quitting smoking is an incredibly awesome change you can make to your life.
Joel's videos are great. I would also recommend seeking out Allen Carr's book "The Easy Way to Quit Smoking" That was very influential to me. It is a great read and it helped me to understand that I was gaining nothing positive by smoking....everything from smoking is negative and quitting smoking is making a huge positive change in your life.
Yes, don't "try" to quit. Just quit. There are a lot of people here who can attest that quitting smoking is very doable and is a great thing to do. Reach out for support here if you are struggling and keep reading up on how to beat nicotine addiction.
I hope you feel welcome here. There is a lot of support and knowledge you can gain here to help you stay quit for good. It is great to have you here.
