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.
I also started checking things multiple times after I moved to uni. But I think that was just because it was the first time I lived away from my family, so I needed to check I've switched of the stove, taken keys with me, etc. When living with my family, I didn't need to care about that as often, only if nobody else was at home when I left.
