I might be anhedonic because I’ve been using methylphenidate for ADHD since 1992, but I’ve always been somewhat anhedonic. To paraphrase Maria Bamford “Some people really love life. I’ve always been on the fence.” The question “what do you do for fun” has always been a bit difficult for me.
Of course it’s also hard to find pleasure in many things if you can’t stay with them long enough for the pleasure to really develop.
