Hi Fearless. This can be a lonely world. I often think, we are born alone and we die alone. All we ever truly know is ourselves.
Nevertheless, the social connection is the most important thing about being human. Why else would we be born into these physical vessels, with these incredible sensory connections to the outside world, with the partiality to love and empathy that we are born with? Have you ever looked at babies and watched as they grow to understand their relationship to the world around them? It's quite miraculous.
Becoming sober is a bit like being born again. We need to learn about our connection to the outside world, inhabiting a sober mind and body. Could you start reaching out, bit by bit? A smile here and there, a friendly word, a little story about yourself ... these can do wonders. Starting to see people as they are ... isolated humans all getting by in this big world. Connecting with one of your fellow humans is amazing and although not every connection may be positive, in time it all adds up to a better human experience.
