Is it normal to keep focusing on a certain part of my body?
Sometimes I'd keep repeating the name of a disease in my mind (it's a kind of cancer, but I don't want to type it here). Also, I'd focus on that part of my body and it actually causes some sort of discomfort. As a result, I'm constantly anxious when this happens... It's like I have no control over my thoughts. I wouldn't say this is normal, but please leave a comment here if you also experience similar thing :(
Fortunately, I've also noticed that it gets better when I'm doing stuff that requires much thinking.
