Physical vs Mental

Yesterday night, i was lying on the bed. Calculating the number of project I need to be submitted and I keep telling myself to endure, cos it's just weeks to go.

Talking about this, i start comparing mental stress vs physical tiredness. Which one is more torturing?

The conclusion that i made was "Mental stress is definitely incomparable with Physical stress." It's really torturing when you need to stress yourself by constantly telling your brain to do this and that. I really can't stand anymore.

Life still have to move on regardless of all this.
