i personally still have most of my social media on my phone, i just have a specific app that blocks how many times i can open the app, and for how long i can use the app for that open. i've been finding that it works pretty well for me at least, the app is called ScreenZen, it's at least on ios.
also, consider that you don't have to be productive all of the time! obviously, if you're not doing your commitments that's one problem, but if you're meeting everything on time then you're fine, productivity-wise. also, don't consider your hobbies to be productive - one way street to not liking what you're doing + doing things that are not productive is perfectly okay!
i (and others who limit time on social media) find it's less about a total decrease in tech, and more how you're spending your time with it, and how you feel about your time on and off it.
also - if you want to do something, but don't seem to have the motivation to do it, try making yourself do it for a short period of time - maybe 5 minutes on a game, or a chapter of a book. i find that helps at least get the ball rolling, that starting is sometimes the hardest part.
this was really long omg, i hope it helps!!
