I'm anxious about losing anonymity.

Any of the things that cause you to worry, or cause you to be anxious about a situation would contribute to you not getting the quality of sleep that is really good.

Losing my anonymity in this world I think is something that I find terrifying.

People bitch about losing their anonymity and then get insulted when someone doesn't recognize them from whatever success they've had.

The world forgetting by the world forgot.

You can never escape who you are, never truly anonymise yourself. Even if you never speak to anyone, people see you, and they get to know you for themselves.
