In Case..

you didn't know.

Into my thirties I go. My cat is growing old. She is dying. My father is growing old. He is dying. I am growing old. I am not dying. But the future is this great, terrifying, black abyss and I have no desire to step into it.

A nameless fear, a menacing fear. Its cause cannot be identified. I guess that's why they call it free-floating anxiety.
