This program might be sponsored by the Church or Jesus Christ of Latter Day Saints (formerly, colloquially known s the Mormons) but they are very good about focusing on recovery and not conversion or preaching and there are meetings you can phone into or go to in person: https://addictionrecovery.churchofjesuschrist.org/find-a-mee...

As someone who has dealt with the selfsame thing you are going through I found their program helpful in helping me get out of addiction (I wasn’t sure I wanted to share that but if it helps you out then it was worth it).
