The speaker is the one everyone leans on, the "therapist friend," who listens and helps but never gets the same care back. The poem is a quiet complaint about that imbalance. The repeated "Always" and "Never" at the start of the lines make it feel like a list of grievances the speaker has been carrying for a long time.
The sharpest moment comes near the end. The speaker works hard to look happy and keeps saying "I'm fine," yet the first small sign of sadness gets them labeled "always sad." It's a cruel kind of catch: help others, hide your own pain, and still be judged when it leaks out. The closing questions, "How is that fair?", sound hurt and a bit worn out rather than angry. The mood is lonely and frustrated, with a plain, direct voice that makes the feeling seem honest and raw. The poem ends on a question, leaving the unfairness hanging.
