Can anyone please take a look of the following paragraph?:) Thanks!

"I will never forget that night, with much agony and sorrow.
That was a full moon day. Glittering and shimmering moonlight reflected from the lake made the scene enchanting until you step in. The news you brought to me was too shocking as though the moonlight turned into a sword and cut right into my heart. "I will never forget you." That was what I thought but I dared not say it as I know letting you go is the best for you."
