To blog or Not to blog

Why am i blogging?! To tell you honestly, i don't have any specific idea why but i think I need this. I have this urge to write whatever i supressed inside before it explode like a bomb. I am a type of person who follows the rule "If you have nothing nice to say, shut your mouth.". I don't want hurting other people's feelings even if they have done something wrong with me. So i believe blogging will help me spit out and let other people know i'm hurting though i won't be able to know who are they.
