Welcome to SR FridayJude -
yeah support is vital...I tried to quit on my own...I found, then, I lacked the self belief in myself or my self worth - I needed to be part of something bigger...whatever that was
You'll find a lot of support here
You may find some like minded souls on our secular recovery forum too:
Secular Connections - SoberRecovery : Alcoholism Drug Addiction Help and Information
Congratulations on your 15 days
