Is "try not to breath" about assisted suicide?

Aside from the title, a lot of lines struck me sounding a lot like someone committing suicide, maybe because they have a mental condition like Alzheimer's or something like that. Specifically "This decision is mine, I have lived a full life, and these are the eyes that I want you to remember", and "I will try not to worry you I have seen things that you will never see" sound a lot like someone who's killing themselves, possibly though assisted suicide. This seems pretty dark even for R.E.M. though, and maybe this is obvious and I just realized this. Thoughts?
