Daniel,
I’m not an expert and only on my ninth day of sobriety but I have found AVRT to help, check out the secular forum for more details. If you google it there is a free online crash course.
There is also a 'sticky' in the Alcoholism forum which lists a range of programs and resources. You have to find what clicks for you.
Well done on making this decision now, it shows a lot of foresight and maturity that I think a lot of us (or least me) didn’t have when we were your age. I am now the grand old age of 37 and wish I hadn’t wasted so much time.
We’re all here for you.,
