It’s not about losing focus while studying. I started college 7 months ago, and since like 5 months ago , I’ve noticed that I lose focus when I’m with people. For example, someone may be talking to me, but I find myself fidgeting with objects around me or stare into space. My girlfriend has also noticed this. She was talking to me, and I was playing with the car window that’s only one example .I really don’t know if I have a problem or if I do this because I don’t care. It happens involuntarily. Could it be from the stress caused by exams from collage , or could it be something else???
