Are we related? LOL My family's all about drama. I distanced myself from them. They hated it, there was drama. But I didn't involve myself and didn't let it concern me. Don't let anything stand between you and staying sober; if it's too much stress do what you need to do to take care of yourself. You can always cautiously edge back later when you can handle it.
And by the way, there's a line between taking responsibility for your actions and taking responsibility for someone else's actions. You are doing well. It's a true statement that your parents allowed you to drink and it contributes to your current drinking problem. There's nothing wrong with saying that, it's true. And to be fair to yourself you have to acknowledge that and not blame yourself for it. You're on the right track.
Good job on 5 days. Make it 6.
Hugs, and welcome.
