Why Can't I Cry by Merle Haggard from his album Out Among The Stars. 

"Why Can't I Cry"
Life comes down so heavy sometimes I can't bear it on my shoulders
I can't cry at all, my tears won't fall as I get older
Guess I'm goin' through a change, I feel so cold and strange
Wish I could fall apart and get it over
Why, why can't I cry like you do when I need to
Why, why can't I cry when I need to
And God knows I need to oh so bad
A woman can cry so easy you never have to hold the hurt down deep inside you
But I can't let go I can't let it show like you do
Guess I'm goin' through a change, I feel so cold and strange
Wish I could just break down and cry like you do
Why, why can't I cry like you do when I need to
Why, why can't I cry when I need to
And God knows I need to oh so bad
