qqp question1: I literally can't control my mind. I'm trying not to think about some things, but it feels like there is something in my mind, some voice who is repeating it all over again and again. I'm scared that it could be some mental problems or illness. What is my problem? question2: I'm in high school and interested in science. I like thinking about problems in my head and mentally solving them. What field in science is for me?
