Ask HN: How to regain my mind back?

Over the last few months i have created a few threads where i ask questions which exposed some insecurities and/or things that currently trouble me. In my last question i asked "How can I come to peace with the years I wasted on pointless things?". The overwhelming number of answers in that thread really helped me. Since then my mind is a bit calmer, and my mental health is more stable. Now, this improvement is probably more due to start taking the correct medication around the same time i made the thread, but i do believe the variety, the diversity, but also uniformity of the answers helped me to put some things into perspective and changed my thinking.

From that point on I took the opportunity to make some small, but crucial changes in my every day life. Some change are: Thinking what i want my daily life to look like, what i have space for in my life, introducing rules on how i spend my time, stop using SM platforms, or limiting the usage to bare minimum for the platforms i need to have some access, exercising and more. The book "Digital minimalism" by Cal Newport informs my efforts. I highly recommend it.

Now, the reason i make this thread is because i have noticed that i «forgot» how to think and engage with others. What i mean by that, assuming that i once knew how to do these things, currently i feel i can't think, It's like my mind has become passive, just consuming without processing. I have difficulties with evaluating information when reading articles or when i participate in conversations, a lot of times i feel my mind blank like i have nothing to say (in serious and non-serious conversations), having difficulty forming opinions besides on basic black and white topics. Another example that i realized fairly recently is that i don't evaluate a comment, a post, etc on my own but rely on others opinions with the comments, upvotes/downvotes, shadowbanning, etc they do.
