I know exactly how this feels. You have put it into words so beautifully. It's heartbreaking, but also something everyone feels at one point or another. I love your wording - it's almost not a poem at parts, just a letter to no one. A venting, but not angry - just contemplating.
My favorite line: "It's amazing, / How gullible everyone can be, / How I can put on an act / And everyone believes it to be true."
Here's hoping you have a good tomorrow - and that your feeling rather careless goes away. Remember to smile!
Keep writing!
