Yes, I experience anhedonia with my depression. It's horrible but fortunately not constantly with me. Comes and goes. I find mindfulness and guided meditation really helpful.

I understand what you mean about the energy involved in interacting with others. I am sensitive to others' energy so if I have difficult or dark energy around me that can be really draining. Sometimes I just wall myself up...something I appear to have learned instinctively in childhood. I would disappear to my room for hours or take off on my bike for a whole day when I got the chance. Interestingly, my family always labeled me an "introvert" in childhood because I was silent and alone a lot. But people who know me in my adult life all say I'm an "extrovert" and I do love to chat with others. I think I was just hiding years ago. To survive.
