Hi Howdy
I think doing things like Artoro is a great idea - especially things where you meet people.
Can you invite some AA folks out for coffee or something?
Volunteering helped me too in the early days - like Anna suggests below.
Things like that are the way social networks get started
I was always very lonely too, but recovery seems to have bought me the gift of being comfortable in my own company - I actually treasure my alone time now - I hope the same will be true for you too
