6th week and battling burnout

I am in my 6th week of nofap. The first 4 weeks were brutal. I burned out at work and feel hopeless as being one of the managements in a startup.

I am confused that my current depression is due to nofap or burnout.

It is becoming easy to avoid porn altogether. But probably my brain is not keeping up with work stress or nofap and past porn consumption are also in the play.
