You might be depressed. Dysthymia is sort of a long term depression.
I feel like I’ve spent half my life just addicted to social media and video games and that’s no longer working.
I definitely relate to this. some time back I kind of forced myself to focus on something long enough to turn it into a hobby. I didn’t stick with that, but I eventually got into playing music again, and I’ve stuck with it for a while now and I’ve built a couple guitars and a bunch of pedals as well.
I think, if you’re anything like me, you’ll have to force yourself into a hobby for a while until it sticks.
