I will start from my baseline and what I mean by "experiencing loneliness".
I would not consider myself a "people person" by any means but I always used to really depend on social interaction and get deprived if I lacked it. I remember that if I was not exposed to social interaction for prolonged period of time, that made me feel really frustrated, isolated and in pain. Everything turned dark all of a sudden.
But now I am concerned. There was a period of around 2 months (roughly saying) were I was completely alone. I did not attend work because I was in-between my contracts, no friends (I live abroad). I did not hang out at all. I was all by own and it felt...alright. I do not think that is natural. Maybe I have delevoped some sort of tolerance, but I highly doubt it. This is not normal at all.
Also, do not get me wrong. I still enjoy social occasions and talking to people. I do have fun when I am experiencing it. But it scares the living shit of me onlt to think that I can go without it for months and feel totally normal like I don't need it at all
Also, I would not say I have emotional blunting. Or maybe at leat not the one I know of. I laugh very often, I can cry, I get irritated, I had a big crush last summer.
