OK sure.
When I stopped drinking, 12 years ago, I did so with the help of AA. That helped me understand why I drank, that I didn’t need to drink again, and how I could sort my life out and live going forward. I also did alot of counselling for trauma and abuse from childhood too.
There are a ton of AA meetings online at the moment, you need a zoom account and can log in and just listen. I found it super helpful to be around people that had been where I was and sorted themselves out.
It’s not for everyone mind, but we’ll worth a shot.
Take things a day at a time, I know you said you have a ton of stuff to sort out which is great, just focus on one thing at a time.
You can definitely stop drinking and sort it all out, I know this as I have done it (and with other substances)
