Sorry Sis, I Love You

She's my big sister,
I want her to tell me how she feels
I want her to trust me,
But I feel so horrible when I can't help her,
I got too much to deal with,
I'm not happy so I go to her,
She'll get me through it,
I know she will,
Because that's what she does,
That's why I love her,
That's why she's my big sister,
It's just when she brings up something,
At the same time I do,
I can't help her,
And it kills me,
I feel so selfish,
Just I have a hard time dealing with more than one thing at a time
I an only take so much in before I explode,
So I'm sorry sis,
I just can't take it,
I love you.
