So This is Grief

I'm not sure how to describe this feeling. I don't know if it's physical or mental - this unwelcome malaise. It feels like I'm coming down with something. I haven't been to a doctor in ages - maybe there's something wrong with me. Or maybe this is plain old garden-variety exhaustion from not sleeping. Or maybe, just maybe, this is how I will feel for the rest of my life.

I understand death; I knew my father would die. I just didn't expect part of me die along with him.

So this is grief.

Does the fog ever lift, or do you simply get used to it?
