Hi CajunPrincess, I was definitely in the same situation as you when I got sober at the end of 2014 and I still occasionally feel lonely but at least being sober means you can eventually try a few things out that involve non alcohol based social interaction like volunteering or arts&crafts. This has the added benefit of occupying your mind at a time when the cravings (for most people) are at their worst
I am assuming that you quit in August so it is still early days, once you have a bit of sober time built up you can be a bit more proactive in making new friends
Congratulations on not drinking last night
