the unspoken problem

Have you ever been so ridiculously stuck on a person? To have such a strong likeness towards them that the one moment that they're with you, keeps replaying in your mind forever and ever afterwards? I've had...this problem...ever since 9th grade, and it's been the same all the time. Yes, if you must know, it's the same person who visits me in my dreams, but who I know is all wrong for me. In fact, he's been in a lot of my dreams lately, showing up randomly at times, but I always remember that he's there. I mean, I don't even know why he's stuck in my heart, he just...is. I have so many voices in my head and along with those voices, thoughts, memories that are both beautiful and disastrous of us. All I can do is what I can at the moment, which is to just be there. But, all this turmoil going inside confuses the living daylights outta me! Maybe I should just not think. Maybe, I need to step back, and watch what happens, being careful not to analyze things, so much...? I'm taught to guard my heart, but at the same time, I'm told to love with all my heart. So how am I to guard myself, when I genuinely love, or vice versa? Hahaha I sound so pathetic right about now I'm pretty sure. But, what is it I should do?
