Am I strong?

"You're so strong"
"You're one of the strongest people I know"
"I don't know how you do it."
and less complimentary versions
"Heart of stone"
"Ice queen"
"psychopath"

And yet when I cry, when I look weak, they don't like it. By 'they' I mean those that think they are close to me but find the truth of it all very uncomfortable. I suspect I remind them of their own weakness and mortality. They like it when I cope, when I am strong because it eases their own fear.

I don't feel strong, I haven't felt physically strong for quite some time. I really don't like it. But emotionally I carry on. But I am not strong, I'm just good at looking like I am. Perhaps that's the same thing.
