Priscilla's poem is about giving everything to someone who won't give the same in return. The hand of the title is a simple, physical image of love and trust. The speaker holds it out, the other person starts to reach for it, then stops. That small hesitation sets off everything that follows.
The feelings shift as the poem goes on. At first the speaker is hurt and bewildered, asking "Why is that?" and calling the situation unfair. Then doubt creeps in, and the questions turn bitter: "Are you really worth it?" By the end the speaker admits to being confused, depressed and close to a limit. The short, plain lines feel like someone thinking out loud, without polish.
The mood is sad and tired rather than furious. The final image, the hand slowly pulling away, is quiet and unfinished. The two dots after "away" suggest the speaker is still hesitating, perhaps hoping to be stopped.
