Dude, the stars are aligned. It's pyjamas and hoodies video season.
I believe most of us are going through similar things. It's kind of the dip before the take-off. A lot of people have spoken/written about it and called it by different names. The common story is that, more often than not, the day defeats the night. After the storm, comes sunshine. Hang in there bro.

About the diet, one binge session doesn't ruin it - as long as you just carry on from tomorrow :)

Also, I love the DTUBE DAILY thingymagit at the back.
