whywork, my heart goes out to you, you sound like you're absolutely exhausted. What you describe as your typical weekend sounds to me like you're essentially always in "recovery mode" trying to take enough downtime for the week ahead, and maybe still never quite fully recovering.
I'm just like you: after a few years of working full-time, my energy level starts to slide and slide until most of my free time is just "recovery mode" activities, and I never feel recovered.
However, it might help you to know that when I've had what for me is adequate time to recover, I find that my energy level gradually comes back up and I start to take more interest in hobbies and friendships and activities again. For example, a few years ago, feeling depleted, I took a year off from work. At the start, I only wanted to watch movies, going on a walk around the neighborhood felt exhausting and unpleasant, and I just felt tired and unhappy. Sounds like your weekends currently, right? However, by a few months in, I was already starting to plan hikes with friends and work on little timelapse photography projects. By the end of the year, I'd spent a full month traveling through Thailand, had taken backpacking trips to national parks, had worked my way up to running 8 miles, was rock climbing a lot, saw friends frequently, etc., etc. I just had to be patient and gentle with myself, give myself plenty of rest, and let my energy return on its own schedule, without trying to force it.
I would wager that you're not an intrinsically boring person as you seem to fear, you're just really depleted right now, and no one has much fun when they're completely depleted. Be patient with yourself; you just need some rest.
Speaking of which, the current status quo doesn't quite seem sustainable for another 7-10 years to FI. Could you alter your plans to get yourself more relief and recovery time sooner than a decade from now? It sounds like you really need it. I know you want to get to FI, but you also want to get there healthy and intact, without having done serious harm to yourself in the process. ;-)
Could you take a gap year like I did? Or even just a few months of unpaid leave at your current job? It'll definitely help you come back to life a bit, and once you feel that spark of energy returning, you can explore some of the other posters' ideas about developing new interests and whatnot. From personal experience, I don't think those ideas will work until then, you'll just be too exhausted to do more than force yourself through the motions a bit, but a good restorative break that gets you fully recovered will lift your energy for months or even years to come, even after you return to work.
If that's not possible, could you maybe revise your FI number downwards to FIRE sooner? I saw in your previous posts that you are aiming for 1.5-2 million to ensure the financial safety of your kids, but keep in mind that they need time and energy from you too! A happy childhood for them will include many memories of family trips with you, camping with you, hiking with you, swimming with you, board game nights, dinners as a family, getting your help with science experiments and school projects, going for ice cream, or whatever else fits for your particular family. You don't want to deprive them of all that for the next 7-10 years (most of their childhood) just so they can live in a more expensive house or have more nice things. They'll cherish the time you spent with them while they were young so much more.
In any case though, mostly just wanted to post to let you know you're not alone in how you feel right now. Good luck and take care of yourself.
