Lyric discussion by manic shmanic 

ummm, okay. i'd like to respond to all the christian responses to this one. believe what you will, but this song is DEFINATELY about depression and suicidal ideation. the first stanza refers to the isolation one feels with depression and wanting to just shake it off like some think is possible but you can't always do that because severe chronic depression is first and foremost a chemical imbalance. the second stanza is referring to the circular nature of depression and how it always leads to the same feelings. the third refers to how when you're depressed you never feel like you can truly accomplish anything, you want to see outside into the light of day and outside of your head and the gradually worsening feeling of being unable to breathe. the fourth talks about cutting and/or cutting open your wrists and falling to the floor like you're so tired of feeling like shit and you want to let yourself fall down. the fifth, "there's nothing left unused here, there's nothing left to say" talks about he's tried everything (including his faith in God if i assume correctly based on the fact that they are a christian band) he can to pull himself out of depression but he can't and there's nothing anyone can say to make him better, or nothing he can say that will do any good to help others understand how he's feeling. "I haven't talked in days, i'm really not too sure what i sound like anymore" refers to isolation and inability to engage in life, maybe literally having locked himself in his room for days unable to get out of bed and function/face the world, and also about doubting whether he's still alive and possessing a real voice or a voice of any consequence. "my vision has gone and my mouth is full of sores" refers to how everything looks darker in depression and how his thoughts distorted so much that he can't see anything that's real, and he's tried to explain how he feels and why he can't seem to pull himself out of it but no one understands and the pain of being misunderstood has created sores on his mouth that makes it painful for him to express how he's really feeling when no one understands or acknowledges his suffering. "i feel like dripping it dry tonight, over and over again, it's time to open up the door" could have several meanings. in my opinion dripping it dry tonight means cutting open his veins until there's nothing left (no blood) to keep him alive. "over and over again" because he's wanted to die for a long time and he also wants to make sure that he won't have to suffer like that any longer. "it's time to open the door" could mean several things. it's time for him to open the door and free himself either by, one, killing himself and leaving behind his feelings of depression or two (which i think is most likely because they are a christian band) opening the door to god or what have you and trying to keep on living. the reason i think this song has little to do with sin becuase becuase the tone of the lyrics and the lyrics themselves suggest no sign of guilt as if he has done something wrong and believes that depression is entirely his fault. also, being depressed is NOT a sin whatever your religious beliefs, although i don't mean to open up that can of worms. thus he has no need to "repent" becuase he has done nothing wrong. if you think depression is something in need of repentance then you are idealistic, arrogant and/or ignorant, incredibly insensitive, and have never been TRULY DEPRESSED yourself to the point of seriously considering suicide.
there you go. take from it what you will.

you are incredibly correct. you must have "experience" with this. the song is amazingly relatable and accurate, as well as intense. my favorite underoath

Like I said in my comment, if you haven't gone through it then you don't know what this song is talking about. But if you have then you know all too well what it's talking about. The song basically sums up everything that goes through your mind while you are sitting there in your room "not feeling very receptive"
