Go hiking every weekend. Somewhere that takes some planning and a bit of effort to get to. I know you said doing things yourself is boring and depressing, and this won't fix the social aspect or give you wild and crazy fun, but it's what changed things for me, when all my usual hobbies and activities didn't. The separation it imposed from my day to day recontextualized everything; it made the job I hated bearable, it gave me purpose each week to figure out where I'd go that weekend, and a task to solve in actually making that hike happen. I felt great afterwards (exercise + accomplished something personal to me), and it started to change how I interacted with the world. It wasn't a magical fix-all, but it started the ball rolling in a bunch of different ways, changing my outlook and how I presented myself to the world, in what I invested in, and it clearly had an effect on how others saw me.
