That's the wonderful thing about ambiguous songs, everyone has the chance to bring their own meaning to it.
I always imagined it to be about depression. 'Dead Letter' being a suicide note and 'Infinite Yes' meaning the actual act of suicide as the answer (albeit imaginary) to the singer's problems. I interpreted the first verse as this person's brain telling them that humans are nothing but destructive and that he is plaguing the earth (ie why be here when all I'm doing is adding to the awfulness of the world.) And I interpreted the second verse as him talking to his therapist and reaching out for help. His therapist then prescribes him antidepressants that will repair his 'chemical imbalances' which might have some side-effects like 'restless sense of detachment, nausea, etc.' The bridge is him fighting with his diseased mind, trying to tell himself, 'You think too much, even your therapist agrees, just calm down,' but then the depression takes over with thoughts of hopelessness, ideas like 'we're alone and we're sick and we just take these pills to shove it all down.' The chorus is, in my opinion, as I've stated about suicidal ideation. The whispers of an infinite end to his sadness come on to him powerfully and quickly. The 'our bodies are dead, why do you look so sad' is him saying, 'I am at peace, why are you sad?' to his loved-ones.
Probably not the meaning, but that's how I'd imagined it since I first heard the song.
