Breaking the habit

Memories consume

Like opening the wound,
I'm picking me apart again

You all assume
I'm safer in my room
Unless I try to start again

Charlie was thinking for the first time about everything. Everything that had happened on the island and everything that had happened before that time. He found out that everything he had done had started and ended with his addiction to heroine.
I don't want to be the one
The battles always choose
Cause inside I realize
That I'm the one confused

The same was with his feelings for Claire. Because of her, he wanted to try and stop with his addiction. However, he had failed and couldn't resist the temptation. Then he tried again, but with the tragic ending of only losing Claire's faith in him.
I don't know what's worth fighting for
Or why I have to scream
I don't know why I instigate
And say what I don't mean
I don't know how I got this way
I know it's not alright
So I'm breaking the habit tonight

Now nobody trusted him anymore, and yet again, everything had ended because of his heroine addiction. He had been weak and would always be weak. How hard he tried the temptation would never be gone, but his feelings for Claire would also never change.
I'll paint it on the walls
Cause I'm the one that falls
I'll never fight again
And this is how it ends
