I deteriorate

Iris Moore's emotions have been numbing for a while. Like every teenager, "woe is her."

But she feels she has to explain to someone
-how she got the way she is now,
-if she's ever going to get help,
-what inhaling and exhaling really mean to her.

She needs to explain it someone so she can understand it herself.
So you're going to listen.

In the end, is she really numb, or is she blind?
