The title suggests a medical verdict, but the poem gives us a feeling rather than a clinical report. The speaker describes being "out of order and cold," as though something inside has stopped working properly. To capture that, the poem offers a strange image: a boat in the trees, silver and ancient. A boat belongs on water, so one stuck among branches feels lost, stranded, and out of place, much as the speaker does.
The second half turns toward release. The speaker thinks they "ought to fall" toward the shore and land among the reeds, like "a clear fruit of water." That phrase makes falling sound gentle and almost natural, like fruit dropping when it is ripe. The mood begins in coldness and isolation but ends with a quiet, hopeful softness. Judging by the imagery, the poem seems to imagine that being brought down to earth and water might be a kind of healing rather than a defeat.
