Surprisingly, it happened, you don't know if it is a lie. You have walked through half of your life journey, you will get the answer, maybe not.
What you must faced now is the two circumstances and its consequence.
If all she said is true, then you'll be happy and your life is meaningful. What you have strived for will get its rewards. Once those tears for her, those days thinking of her, should be of its preciousness. You can say that you are well and grateful. This is not enough, the world is amazing, out of people's imagination, we are lucky.
But what if the other side? Then your life is a thorough failure. It has no meaning, because it is a lie, the so called dreams is a lie, the endeavor is vain, the emotion is ridiculous, you just put all of your energy to fulfill a lie. What a tragedy!
To be or not to be, that is a question.
