I am a heavy cloak, draining all your zest, Making even exciting things seem dull, at best. What am I?

I see your success, and it stings like a bee, Wishing what you have belonged to me. What am I?

I cause tears to flow and make you feel blue. What am I?

A voice in your head whispering doubt, making you question if you'll ever figure it out. What am I?

I build up in your chest, a hot, fiery core, Ready to burst at a perceived slight, wanting more. My voice can be loud, my actions may sting, But sometimes I just need a moment to swing. What am I?

A knot in your stomach, a twist and a churn, Worry and doubt, a future uncertain. Exams and decisions, a test of your will, But facing me head-on can help you stand still. What am I?

I make you blush and stammer your speech, Wishing the ground would open up just out of reach. What am I?

I wrinkle your nose and make you say "yuck!", from spoiled food to a dirty old truck. What am I?

I bring sunshine and laughter, a feeling so bright, Making everything seem cheerful and light. What am I?

I come with a smile, but may not be true, Hiding what's really there, just for me and for you. What am I?

I think of memories, happy or sad. What am I?
