In my experience, 9 days aren't enough because you haven't experienced enough of the benefits of being sober to make an informed decision.
The single greatest benefit for me is that I'm not spending every day in a furious inner debate like your first post, above. All those data points are irrelevant, because at nearly one year, I know in my gut that I have a better life and I am a better person sober. And many of the benefits really didn't materialize until six months or so.
There are people who do just fine with just online support. Others do well with individual therapy. There is no single path that works best for everyone.
Wishing you well.
