Can't do presentations

[anon0]

I have an incredible fear of doing presentations or even speaking to/in front of anyone other than the 2 people I'm close to. Every time I am told that I have to do a presentation I immediately start panicking and continue thinking of it until the very moment it happens. When i have to do a presentation I physically can't do it. I get really hot and sweaty, my entire face gets red, I find it really hard to breathe, I start shaking and crying, I feel like I'm about to pass out and my voice physically can't come out. I also get heart palpitations. Up until now I've asked my teachers if I could only give them my assignments and to deduct marks for the presentation. I've tried multiple times to train myself to be able to present but it never works. I really need to get over this and find a way to at least be able to speak and breathe while presenting and not be so terrified of it that I panic every single day leading up to it because I can't keep putting my grades at risk. I'm going to univeristy next year and I know that if I don't do a presentation it will affect my marks really bad. Please if anyone has any suggestions let me know because this is something I've struggled with for a long time now and it's had a very negative impact on my grades and social life. Thank you.
