Welcome Kelly, thank you for sharing. There is a lot of recovery material here on the site. The Just for Today readings are from NA.
We don't quit with the thoughts, I can never use again. For me, it is just for today, I choose not to use, no matter what. There are tools in the program to help you live each day clean sober.
Hope you will keep coming, only you can really help you. You have to be willing to quit. Many times I have had to pray for the willingness to be willing.
