Getting even MORE single?

I was wondering, really asking people who have been doing this longer than I have (about a year in my case), if it's common to start to so much settle into singleness and solitude that you start to spend less time with friends as well because even that feels like too much effort.

There's a certain amount of playacting that I find around some friends that I just don't enjoy anymore. I feel like most of it goes unnoticed by most people, it's in the little things, the things you don't say (but think) the things you listen to as if you're interested, but don't actually care about, finding them to be a drain on time and your energy because you can't really be real.

I always thought the term energy vampire was kind of silly, but since spending much more time alone, I'm surprised by how much more energy I have, both physically and creatively. It's like having a whole new lease on life, and it's only increasing over time.

But there's a little part of my brain that's wondering if this is somehow maladaptive? Or secretly a sign of something that's not ideal? Generally when people withdraw socially, it's considered negative. Thoughts?
