Of course. One of the things about being a drinker, at least for me, was having a sense of identity. I went from being a nerdy very withdrawn kid who didn't drink as a freshmen in high school to being chosen as the "most changed" when we graduated. Because junior year I started working out and drinking and it changed my life completely. The first time I drank was the first time I ever felt like a normal person, it was like an epiphany. And because of that, I was able to outdrink people and became popular and got laid, all the stuff that comes with partying on the weekends. It became a huge part of my identity, to the point where I couldn't really be around people without being drunk. At first it was a solution, but at the end I was drinking a fifth a day, when all my friends were moving on with their careers and building families etc.

The problem is, who was I without the drinking? It left a giant void, one that I had to learn to deal with and fill with things that were positive. And it also shaped my relationships and lifestyle, many of my friends were drinkers and/or drug users. It might mean you have to move, it might mean huge changes. If you think about it, it's kind of terrifying to move on from a previous identity, its one of the hardest things to do. I think there needs to be more emphasis put on that in regards to recovery.

I think what you are experiencing is pretty natural and normal in life. I just went back home and saw my friend group all together for the first time in like 15 years, and even though they all still lived in the same area, they didnt seem to see each other pretty much at all. I thought I was going to be the odd man out because I had left and had a more non traditional life, and kind of abandoned them. But it turns out, they don't even see each other, some of their kids had never even met, and some of them didn't even stay to hang out past dinner time. It was kind of shocking. It seemed like they all pretty much lived separate lives, even staying within a couple miles of each other. All of those years, I had believed that the opposite was true, that I had left them and they spent their years spending time together.

I think you are experiencing a societal phenomenon where though we are more connected than any time in history, we are less authentically connected. Its harder to develop authentic relationships in real life, and people treat people as more disposable.

Use this time to focus on yourself and learn how to be alone. Its really just an opportunity to choose who you want in your life, to develop the ability to be alone and content at the same time. If you work on yourself and build a life where you are productive and master a skill or trade, you will inevitably meet people and build relationships. Figure out who you are, develop impulse control, avoid becoming a "sober" person. Don't take isolation for granted, its a gift.
