Welcome back, Michelle. You have tried to quit many times, this time it needs to be your forever quit. Please stick around, lots of support and knowledge you can get here.
Just remember, nothing good comes from smoking. It is just a short term illusionn of relief but really it just adds to your stress level by continuing to feed the addiction. Quitting is the best thing you can do long term. Oncce you quit for good, things do get a whole lot better and it is worth the early struggles.
You should be able to edit your quit date by clicking your name in the top right navigation (if you are on a laptop or PC), click on "Edit Profile" at the top, and then the screen that appears should show you your quit date. You can edit it there.
There is also a tab at the top that says "Ticker" which will show you how to create a new ticker.
Hope that helps and hope you stick around. Quitting smoking is definitely doable and something you really need to do, Michelle.
