Tips for Oral Presentations/Speech I really need help!?

[Hey]

Okay so next week I have to do a power presentation. I for some odd reason like being funny with my friends I like being that funny kid among my friends and being around attention however whenever I hear the words, speech, oral presentation, my stomach sorta drops and my nervousness kicks in. I hate it. It really kills my mood because I can't get my mind off it. When I was small I never had a problem with public speaking but as I got older i got more embarassed. The last time I did a speech i practiced realy really good that I had everything memorized and we didnt have a paper we had to memorize this story. So when it was my turn to go up there I literally my mind went blank I said the first part of my story and I just panic and I let the nerves get the best of me. And now I have to do this presentation and Im really nervous but the weird part is im not sure why. I really dont care what people think of me. Its just that three days ago was the original day that we were going to start presenting and my whole time in the class I was breathing too fast and was freaking out but we ran out of time so no one presented and now we're presenting tomorrow or next week. I tried everything. I ate oatmeal because i heard it calms your nerves. I even breath slowly in out so i cann get my breathing but that doesnt seem to work. What i experience is that I soon as i get up there I feel this very akward mood when my name is call to go up there its just the classroom is so quiet and im up there presenting that just gets me nervous where everyone is staring. I have friends that dont get nervous at all and I just wish I was like them they have this confident attitude i tell them im nervous and their respond is like yeah im not nervous its like whatever I just tell myself not to get nervous. I know what i have to say and everything its just i experience the symptomms of nervousness. I know i wrote alot but yeah I hope i dont have any serious public speaking fear issues. Any tips or ways that helped you overcome public speaking to the point that it didnt matter when you have to do one. Thanks alot guys for all the help!
