Hmm, I don't know if what you said would be emptiness for me, but it is something I experience. I definitely work better with encouragement.
For me emptiness is just that - nothing. I feel nothing, do nothing, just a whole lot of nothing. Luckily I don't feel truly empty very often, but I do constantly feel like something is missing for me. For me, that's someone I can be close with. I don't have that. I have a couple of people that I can sort of rely on, and I'm grateful for that, but not quite what I need so I do feel emptiness in that part of me.
