My Sister, [I'm sorry]

I just don't know what to do anymore,
I feel like my perfect pretense is gone,
You've seen what's in my very core,
Seen everything that I've done wrong,

My heart breaks at being exposed,
Tears run down my true face,
Everything I've tried to keep closed,
It's been nothing but a waste,

Do you think any less of me,
The happy sister you knew is a lie,
I know that you won't be able to see,
The reason that I now cry,

I tried so hard to be who you wanted,
I guess my best try just wasn't enough,
My heart feels weighed down like lead,
Even though you say you went through the same stuff,

Somehow I can't believe a word you say,
I'm sorry that I can't believe you care,
I struggle through each and every day,
Every moment like a nightmare,

So I'll make new masks that you can't break,
Hide behind my impenetrable walls,
Sure you can try to pick and take,
But this time I'll make sure I won't fall,
