If someone can "commiserate" with you, it means they:

To commiserate means to empathize with someone else's misfortune or distress. When a person can commiserate with you, they are able to share in your feelings of sorrow or hardship, indicating a strong sense of understanding and compassion for your situation. This shared emotional experience can provide comfort, as it acknowledges the difficulty one is facing.

The other options do not align with the meaning of commiserate. Feeling joyful contrasts sharply with the notion of sharing distress. Indifference suggests a lack of concern or empathy, which is the opposite of what commiserating entails. Offering advice implies a more active role that seeks to change the situation rather than simply sharing in the emotional experience. Thus, the correct understanding of commiserate is rooted in sharing feelings of distress, highlighting the importance of emotional connection and support.
