I get lonely, but I feel it more poignantly when I'm in an office and everyone is taking in groups, sharing personal details. I don't know how to get into such groups. I fail to resonate with what they discuss, and generally am faced with a demonstration that I am alone. Put me remote and I can get by just fine with some casual jokes on slack. I can lurk in channels where issues that matter to me are discussed and tune out when it doesn't apply, and there is no anxiety because people dont know not care that I am "present". Not saying my practice is healthy socializing, just saying that putting me in physical proximity of other people does nothing good for my loneliness.
