Public speaking.

I hate oral presentations. I get so nervous when I'm about to present and just today I was doing a long presentation about Global Warming, my mouth was dry as fuck aaaaanddd it was 15-20mins long. I got so nervous everyone was just waiting for it to be over so I just read quickly of my powerpoint slide.

Anyone got some brotips ?

I got that problem too.
With friends etc... I talk normally but when doing something with someone that I don't really know my mind becomes blank.

Even when I talk to someone in English the same things happen.
English isn't my first language
