Dear friend, at some point in our lives, we will have to face a dilemma and you can only make a choice. a choice that determines how your life's gonna be. you know that you've changed and that you're not yourself. you want to be your old jovial self again but you cant bear to give her up because you're so in love, so smitten with her. its as if she's like the air you breathe, without her you'll die. In life, you have to make sacrifices, i know its gonna be hard on you but hey, "sometimes a sacrifice might be a blessing in disguise" quoted from abigail. plus, you're at an age where you're in the puppylove stage. you dont know what love is. its conspicuous that she doesnt love you the way you love her so much. i just dont get what you see in her, she's only using you. but who am i to interfere or meddle with your heart's affair, who am i to even have the rights to say that she doesnt love you when i all i know is she looks really bitchy from the exterior. come back to your senses my friend, dont ruin your life, stop sulking and being depressed about how she broke your heart. she's not worth it.
