I personally think this song is about someone going insane due to insomnia. I get this from the phrase, "Bloodshot eyes." and "Self-torturing". For my interpretation of the singer having Insomnia, I can tell this by the words, "My eyes are stapled open" and "I can barely shut my eyes". To prove they are losing sanity, I'll use the quote, "My sanity is spent.". Overall, the possibility of them being insomniatic is from the quote, "All insomniacs, please raise your right hand". BOOM! Finished.
