Together Yet Shattered

You have reduced me to pain, anger, and sadness.
I rejoice in the good times,
They are so little and few.
Though they are sweet and short-lived
They are what I exist for.
But rarely any of them are with you.
You have made me hard and cold
And my skin is rarely penetrated.
But when it is I am happy for a brief second.
Before my shell heals and comes back again.
Then you come back and apologize
And assume everything is fine.
But it's not.
Inside this shell my organs are shattered
And I long for the day they will be glued back together.
But if no one can get inside, how is that possible?
I certainly know I won't be letting you in.
