It goes beyond the internet. The real world is an excruciating parade of torture, and no amount of self-platitudes or of positive thoughts will change the reality of the situation.
Sure, you can try and not have anxiety. Live in the moment. But someone is eventually going to take advantage of that and you'll be worse off. That can only happen so many times before you start reevaluating your thoughts, intentions aside.
Personally, the only times I've ever felt good about the world and how everything was going to be okay have been when I'm using opioids, hidden away in a corner of my room.
