Forced to Be Strong

I was always strong
Always strong for you
But I can't be anymore
I've felt too much pain
Pain for years
And now I'm getting weak

My knees want to buckle
I have my weight
Your weight
The whole worlds' weight on my shoulders
Laying on my shoulders

I can't be strong anymore
I can't take all the names
All the slaps
All the punches
Do I get my turn to be weak?
