I feel like this is the root of most of my depression. I constantly feel like I'm not trying hard enough unless I'm suffering — and that my productivity is determined by my pain threshold, which always has room to grow.
But why do anything if I need to torture myself to do it? What's the point? Why not just lay here in bed all day? It's so much easier.
It's not surprising that I spiral into the abyss when my thinking goes in this direction.
