Something intricated

From the text, besides the word UNCERTAINTY being highlighted, KEEP THE PAIN is one of the core message delivered through the whole text. Yes, pain strikes, arises, and persists. After three long years, pain has never faded. However, all the doubts and fears stopped mainly because I had learned my lesson. Never to fight a war that I'll never win. But this does not indicate that I withdrew. I will sit back, and wait for the day when retaliation comes. Perhaps just like how the saying goes, ignorance is bliss. I will take whatever life throws in. For the worst came, and I am immune to the unjustly side of life. If I had a choice, I will backspace the last sentence in the text, as I've always been unappreciated. Period.
