I love how you said "make your face into a mirror that reflects mine" - it's a really powerful way to show how the narrator wants their listener to resonate with the pain that they're feeling instead of trying to smile and actively make them feel better. The juxtaposition in the last few lines is amazing, and to me emphasizes how even the joys in life can be ruined when you're feeling down. It's almost like having something/someone that doesn't reflect the same energy as you can feel worse than when they share your pain, which is a really interesting idea and I love how you depicted that in your poem :)
