I live alone. I have pretty much my entire adult life. For some reason, I have no issue being by myself. I can spend days and days never speaking to anyone. Life through the COVID shut down didn't impact me whatsoever. Did I "miss" seeing folks more regularly? Sure. But I didn't once feel lonely, or even alone. At the end of the day, we are all just different people with varying degrees of a multitude of traits. I just happen to be someone who can be alone without being lonely. In fact, I don't recall ever feeling lonely.
This all said...I'd rather not be truly alone. I love my friends and family, and I enjoy every minute spent with them.
