Good for you! I deleted all social media from my phone except Instagram. I like to get a chuckle looking at memes before I go to sleep. But even there I set a timer to warn me when I'm on there too much.
Like you, I am not dependent on social media in any way. I would delete Facebook, except that it helps keep me in touch with friends and family in different countries better than any other app.
I retweet to help amplify messages, but I very rarely reply, and basically never post something on Twitter. Why would I? No one gives a fuck what I think, and I don't give a fuck what some rando on the internet thinks about my opinion.
I have one subreddit I like to follow and post on, but in times like now when I'm busy at work, I don't even do that. It is much easier to dial back the last bit of social media if you've already deleted/dailed back most everything.
I made all these changes a few years ago, and I use the time to read more (i.e. my medium membership!), and read more widely. Very happy with my decision, and I don't see me ever going back.
