Yeah, I moved to uni a few months ago. I feel like I'm double/triple checking things (like whether I have certain things or did certain things) every 15 minutes or so, and it's not normal. Seeing the counselor soon though.
Are you afraid of failing at your study? Because I had that too, only my response was not to study, so I would fail due to lack of effort. Your response might be abit overzealous, but atleast it is positive
