Imformative speech

Something i know about informative speech is we tell some information to audience about history our life. For this time i must talk or share with my class about "my self".Actually, not many history that i can share with you all but what can i say is i have a big family and i the second last from my family. For starting talk fronts of my friends and my lecturer i feel really nervous and my heart deep so fast.. Then i feel nervous because i have to tell it in front of the class, some thing like that i not alwasy do, to speak fronts of people and many eye focus on me. From my nervous  that impact on my speech, my mind blank, i can’t think wisely.But my power point help me to much to give the point what i can say ant story to all my friends. Many think on my mind but only few come out from my mouth. From what happen i learn a bit how to manage my nervous in public and i try to improve my self.
