I Can't

"Ha Ha Ha!  Look at you! Look at your Nails! They're sooooo long!"
Their words cut deep,
But I don't say anything. 
I keep it inside, 
No need to retaliate right?
But,
Every. day, 
It's.
The. 
Same.
Thing.
How long can I keep doing this?
I guess I'll find out.
One day,
You do it again.
This time though,
I snap.
I start screaming, shouting.
Everything they've said,
Everything I've felt,
It comes out. It feels good. 
But they don't like it. (no surprise there)
So I swallow it.
I try to control it.
I really do. 
But they don't understand.
They never have and never will.
I. Can't.
