I knew something was wrong when I first noticed that I was feeling anxious for wanting to do something that I enjoy, and that the anxiety has been slowly killing off all of my interests. I'm so calculative that in order to prevent wasting 2hrs of my life watching a movie I wouldn't enjoy, I'd spend hours browsing through the whole catalogue and going on IMDB to check out the rating for every single movie, then bookmark them and end up watching nothing.
The same thing for Spotify. Never happy with my choice of song. But when a good song comes up on the radio, I totally enjoy it.
I miss being spontaneous and going with the flow, and I'm working on "going back" like you too, by reminding myself to be contented and live more in the moment.
