Does relapsing restarts the Flatline?

Hi guys,
I was on day 20 and probaly on a flatline.Because I was feeling extreme depression and boredom as well as Completely Zero Motivation.In the noon I was lying on my bed with surfing the web.I subconsciously watched and masturbated.My depression got worsed.In the next day probably after 24 Hours.I noticed that my depression and boredom has been decreased.I was also feeling little motivation.in that day I went on a pmo binge and masturbated 2 times.And in the next day I noticed that my depression and boredom has totally gone and I felt extreme motivation.Please Can anyone explain this.I have felt the same thing in my past NoFap attempts.

 

Thanks.I'll update soon

 

I have noticed that the flatline disappears when I relapse and comes back when I get into NoFap challenge again
