!!! Trapped In Life !!!

I never understand what exactly is the need for following others?? Can't a person be what he/she is?? Can't a person speak his/her mind out without thinking what others would think of him/her. It happens to me when sometimes I am engulfed in a desire to say anything and everything. Its like just to discuss the very thought that I have sometimes. But its not considered good to speak too much, and at others, it is not considered good to talk anything senseless. But what about the emotions and feelings that dwell deep inside one and try their best to surface out, but are forced to push deeper within, and these keeps on accumulating inside one, and then one day escape with a burst.You know what I am doing right now. I am just speaking my mind out, I am saying anything because I feel like saying it. I know to most of the people it is senseless, but then I don't care about anything, as I can be the most careless and insensitive ones at times..:-)
