Missing you

Missing someone so much..can't deny it anymore. It's makes me feel like I'm drowning into a very deep sea water. My soul became empty and bitter. Don't know why I keep missing that person.
Dear old me...I really missing you. I don't know something keep disturbing me. It's look like I'm doing lot of bad thing in my past. So it's keep me missing my old self.
Guys don't get me wrong..zaman kanak2 and remaja saya is fantastic, enjoyable and happy. Just..just...arghh really hard to explain this feeling btw.
Maybe I had done something horrible, stupid or crazy that time but I'm not sure what is it. I'm insane is it??
