In Emily Dickinson's poem, she reflects on her complex relationship with grief and joy. She feels a strong capacity to endure grief, suggesting that she can navigate through deep emotional pain with familiarity and strength. This indicates a certain resilience, as she has become accustomed to heavy sorrow.

However, when joy enters her life, it disrupts her balance and stability. The metaphor of joy as a 'New Liquor' highlights its intoxicating and overwhelming effect on her. Even a small amount of happiness can cause her to lose her footing, symbolizing her vulnerability to joyful experiences compared to her strength in facing grief.
