Thanks for the suggestion. I actually do a kind of yoga (though more focused on long poses and stretching) and it indeed does help. So does working out. I do feel calm and content while doing it, but that feeling does not last very long beyond the practice. Once I get back in front of the screen, it's back to the usual self.
One more suggestion: try cooking classes, HelloFresh or just YouTube lessons. Preparing and serving a good meal three times a day helps a lot to distract from what’s behind the screen and also offers enjoyable experience, that you can eventually share with someone.
Maybe you found the key. Don't sit back down in front of the screen unless you have to. Fill your day with enriching activities, instead of filling your day with screen and breaking it up with the occasional enriching activity.
