These are powerful words. And true words. I’m glad you have accepted them.
I believe it is entirely possible to overhaul our life, change our ways, begin if not again, then at least once more, and transform into better, healthier, happier people from the broken lonely hurt nonfunctioning messes that we were. At the same time, I would like to stress that this is up to ourselves and the work we put in. You’ve chosen AA and Church and these are good, trusted, powerful tools where you can apply yourself and do your utmost to grow and change. Given to you is only the possibility - the resurrecting you’ll have to do yourself. It is wholly possible. It is a life long work of awareness and self care and other care.
Here are some more resources to add to your toolbox:
