The speaker describes therapy as something gentle and nourishing rather than frightening. Many people expect it to hurt, so the poem pushes back directly: "Therapy is not torture." Instead, it is shown as a slow repair, working "word by word" and "wound by wound," like someone stitching a torn heart back together.
The speaker feels encouraging and warm, almost like a friend urging you not to give up. The imagery is playful and homely. Therapy is something to "taste" and enjoy like a favorite sundae, and it becomes a "mint flavored glacier" that cools an overheated heart. Even the mind is pictured as a companion to play with, not an enemy to fight.
The mood is hopeful, soothing and a little sweet. The closing image of a "feast of poetry" suggests that healing can be a kind of beauty, something to receive with open arms rather than escape.
