You aren't alone with this. I'm so obsessive. I've had a crush on a friend for years and years now - was there when I was sober, drinking, doesn't matter. I can also fall into addictive patterns with working, running, junk food, etc.
It's probably easier for me to list things I don't have the potential to get addicted to!
I wish I knew how to fix it. I feel like drinking or not drinking is just scratching the surface.
