Sometimes.

Sometimes it's hard to tell is you really look like a size ten or if people are just being nice.

Sometimes it's hard to tell whether what you're feeling is pain or whether, because of the numbness, any feeling at all automatically means pain. Is this hurting? Or is it all in my head?

Sometimes it's hard to say no when you know there won't be anyone there to back you up.

Sometimes it's hard to smile when your mouth won't move that way.
