I feel you. You should really try to go back and watch some documentaries or movies that you've never checked out. There's plenty of classic TV and Films that can be a blast to enjoy. It's like a glance into the past at a bygone era. I've been seeing a new girl recently and we also really enjoy watching old movies and docu-series — neither of us are particularly into TV, though. Board games can be another really fun one, too.
Just don't get lost in the rage/clickbait. Be sure to take time to enjoy life. The miserable aspects aren't going anywhere. As long as you have each other you can explore new things that you both enjoy.
