This was a big thrill for me when I was drinking.
For me, it was symptomatic of my acute social anxiety which told me that bottom line, I was lonely. Drinking took the edge off and the social mediums gave me the distance I maintain even as sober.
So part of my recovery is to gently but with purpose, step outside of my comfort zone and isolation, and start to socialize through mediums conducive to sober living: hike groups, community gardening, even the gym!
