I was not withdrawn before, but now I am withdrawn and like to be alone. Later, a fortune teller said that I would live in seclusion in the mountains in the future. Is it possible for me?

I don't think this is possible. First of all, with the progress of society and the development of human beings, it is too difficult for you to find a forest without people. Secondly, if you want to live in seclusion in the forest, you need some money first. Otherwise, why can you live in the forest? Can you live like people in the past? Finally, you have become withdrawn now, which is caused by your unsociable. As long as you open your heart and accept some emotional training, you will get along with everyone easily and get happiness from it. At that time, even if you were asked to go to the forest again, you probably wouldn't want to go.
