Although it may make you feel better temporarily, your attitude of superiority over others is a fragile defense. Yes, there are people who live lives of self-deception and fear. Yes, there are therapists who are burned out or who listen to others solely for money. But I think such people are exceptions. Most people, including most therapists, are doing the best they can to live with integrity and gratitude.
Nature can be a powerful source of healing, it’s true. But in your case, I’m concerned you are using it as yet another way to separate yourself from the human condition. You would be better served if you would engage with your fears about the social world and learn some humility. People are pack animals. They are not meant to live in isolation. We become our best selves in the joy and the struggles of being in relationship with others.
There are many, many people who are struggling with the same philosophical and spiritual questions and who would welcome talking to someone like you who has such an inquiring mind. I don’t know what has happened to you that you can’t see them or are afraid to approach them. Therapy would probably help. Since you can’t afford it, please take a look at this article for resources: https://psychcentral.com/lib/when-you-cant-afford-psychotherapy/
I wish you well.
