Completely heartbreaking! You have a talent for lacing emotion into your work! There are only a few technical errors that I found, but they don't detract from the poem very noticeably. First,"Daddy if I invite you to my tea party will you stay?". There should be a comma before "will you stay?". Lastly, "use" should be "used". All in all, you've got a great piece here; keep writing from your heart, and you will find more beauty and reality in your work than many who just crank out stories!
