Have I become heartless?

Sometimes, I really feel that I've gotten 'heartless' over the last 2 years.

My vocal teacher says I'm unemotional when I sing. My HODs say I look very calm and forbidding. TOO calm and forbidding. So many of my students ask me to smile more in their Teachers' Day cards.

And frankly, I really didn't feel much when I was told that my favourite student is hospitalised. And when I went to see her today, I also wasn't feeling much.

I'm so afraid... Has my heart really turned cold? Maybe it's disappeared...?

So that I will not get hurt. By my students who hurl vulgarities at me so often. By my HODs and P who think I'm not a good teacher. By the guys who don't seem to be interested in me. By myself for failing as a form teacher. As a subject teacher. As a woman...
