Struggling to do nofap in a new environment

Hi guys, im really struggling at the moment. Earlier this year I started nofap as fapping was making me depressed. At this time i was working full time and had a set routine and was near my girlfriend. I managed to do a 100 day streak.

Now im at university, living away from home and away from my girlfriend. It’s a real struggle for me in this environment to get past 1 week compared to before. I really need some help cos i’m really struggling at the minute and keep fapping after 7 or 6 days every week. Any advice?
