relapsing on weekends

Hi, I am a college student and I have two jobs.
I figured out my cue about this incessant relapsing.
It's when I play with my cell phone or talk to the girls online, I get horny and relapse.
my furthest streak was a month and that was when I was in a military boot camp (no cell-phone allowed).
Anyway, Since I don't work and study on the weekends, I relapse on the weekends.
I go for a walk occasionally but I want to see if there are any other tips I can apply at home during this pandemic.
Also, when I freak out or be anxious about something, I relapse.
It looks like one of the hardest challenges in my life
Please help, Thank you,
