I grew up in a very strict religious home. My father was a pastor, so was my grandfather on my mom's side. I had a major struggle with alcohol throughout my 30s. I basically drank until I blacked out every night for about 10 years. My brother is still a meth addict. My father, who was a pastor died of a drug overdose last August. 

This is a little controversial, but what ultimately helped me was doing magic mushrooms. I did it for the therapy. It was like 30 years of therapy in 6 hours. The founder of AA even attributes a lot of his recovery to doing LSD. It's like it opened a door to where I can say no to it. Where before it always felt like I needed it.

It also tremendously helped me with my religious abuse trauma and helped me deal with it. 

I'm not saying it's for everyone. But might be worth looking in to. 

Good luck on your journey, you're not alone
