Step 1: Understanding the Question:
The question asks to identify the specific feelings the poet experiences, as mentioned in the poem.
Step 2: Locating the Information in the Passage:
The first stanza of the poem directly answers this question.
- Line 1: "Sometimes I feel all thin inside"
- Line 2: "Insufficient, small;"
- Lines 3-4: "I feel when people look at me, / They don't see me at all."
Step 3: Final Answer:
The answer can be drawn directly from the opening lines. The poet sometimes feels physically and emotionally diminished ("thin inside," "small"), inadequate ("insufficient"), and invisible to others.
