Useless

Sometimes I think one of the most hurtful things that a parent can say to a child is that 'you are of no use' or 'you are useless'.

I heard him say I was useless probably ten times a day. 
Over the years I eventually found a way. 
I convinced myself he didn't really mean it just to make myself feel just okay. 

But every time he said it in passing or in anger, it hurt me just a little more.
It seemed the older I got the more it shook me to the core.
I wonder when can I ever say, Dad, stop, no more.
