Eating is a CHORE

I had my vsg in October and am 4 months out now. I've lost over half of my excess weight and I feel so much better physically (BP is good, no lower back pain anymore, no longer pre-diabetic) but eating has become a very tedious activity and it's exacerbating my depression. I just couldn't face another high protein breakfast last Thursday and stayed in bed as an avoidance tactic.
I'm still eating and getting my 80g of protein each day, and food doesn't make me sick or nauseous. I can eat just fine. It's not physical, it's like a mental exhaustion. I'm having a hard time putting it into words other than eating has become a CHORE that makes me kind of sad.
