Sometimes love can be a bullet straight to the heart. I know exactly how you feel. I am currently in love at the age of sixteen and although it may seem as if I am not mature or 'old enough' to fall in love, I can tell you that I shockingly am. It hurts, rejection and all that other nonsense stuff....but there are many things that occur do to the way life is.
You live your moments and suffer the consequences. It is how the world works. I hope you pull yourself through this.
