The title is half of seven; a number seen traditionally as the perfect number in various cultures and in many religious contexts as well (other mention of less than seven being less than perfect is in Transference).
Continuing with the religious symbolism, the song’s lyrics could be a reference to...
Why am I this way?
Tell me why
Why am I this way?
Why?
Open wounds in the palms of my hands
Festering through infectious time
I feel so faint as my life spills over you
Backstep over glass as I repent
I fear I cannot prevent
Myself from spilling your life all over me
I'm so sick, so sick of myself
Mother, say you'll pray for me
I'm so sick, so sick of myself
I'm premature in my decay
I'm so sick, so sick of myself
Mother, say you'll pray for me
I'm so sick, so sick of myself
Shards of glass swimming in my eyes
A small voice in the back of my mind
That's whispering words I never want to hear
I pray that you won't hesitate
As you watch me degenerate
To reach in my wounds and extract all of my fear
I'm so sick, so sick of myself
Mother, say you'll pray for me
I'm so sick, so sick of myself
I'm premature in my decay
I'm so sick, so sick of myself
Mother, say you'll pray for me
I'm so sick, so sick of myself
My suffocation
Asphyxiation
I've been choking
On my own blood
I'm so sick, so sick of myself
Mother, say you'll pray for me
