I'm so sorry he said those things to you. It's not something that's going to help you. I know how that goes. I have some family members who would say those kinds of things and not think twice about it. It does come from a negative place. You have to rise above them, truly.
Toss out the alcohol, because it's only a waste of your time. It's digging you a deeper hole.
The best way out is through. That means no escaping allowed. Escapes are illusions.
The best thing is to go on and live your life, sober, and leave those family members nothing to talk about. They will be left to deal with the fact they have a juvenile mentality when you're getting healthy and moving on.
