Your anxiety disappearing after three months isn't a phase - it's your brain telling you loud and clear what's actually good for you. But don't mix up "no social media" with "no social life" - your friends are getting that wrong, and that's exactly the trap social networks create by blending them together. You can absolutely stay connected to the people who matter without the apps: texts, calls, meeting up in person, that still works great in 2026.
The thing is, happiness without this stuff is possible, yeah, but you gotta be active about finding alternatives. If you just disappear hoping people will chase you down, okay, there are risks. But if you keep your relationships going some other way, you're gonna find you gain time and mental clarity without actually losing anything.
