Hi BetterLife,
I'm glad you're back and working on recovery
It's good to remember that stopping drinking is one thing, and staying sober is another. As you said, you feel like you're missing the fun, so it's time to set out making lifestyle changes to support your recovery. Maybe you can start a new hobby, or get involved in sports, do some volunteer work in your community (also a good way to make new sober friends). You can create fun and enjoyable times in your life.
