I am a diagnosed anhedonic so the thought of this comes up often. People see fun in such things as trips as automatic. I wouldn’t say it’s not a thing, but it’s like, where is the fun if not in name if it doesn’t just come to me? There was one at a venue where at one point my ability to “be in the moment” was questioned and those I went with made a large scene because I was “unenjoyable”. Stage-frightened me was ruined for the week after that, and now I have even more questions when an event arises.
