Emotional memories wiped clean

I've been battling anhedonia for almost a year now, still not sure if it's part of post-acute withdrawal from quitting weed 7 months ago or if I now have depression. I'm a big movie, music, and gaming fan, but my anhedonia has prevented me from enjoying all of it. It's all just bland nothingness now. Not just that, but all of my feelings and opinions of my past favorite movies, music etc. has been basically erased? It's as if the part of my brain that is responsible for loving things has been surgically removed. If someone were to ask me if I like this song better than that song, I would simply reply based on my memory of what I used to say before it started, not because of how I'm currently feeling...because all feelings are gone. The Dark Knight is my favorite movie of all time, but if I were to compare it with a movie I really hate, they kind of just feel the same? Is it like this with anyone else?
