public speaking

Hello,
I am looking for tips or help or anything useful when it comes to a fear of public speaking..I have an immense fear, and it leads to panic attacks pretty much every time I have to get up and do it. I can't breath at all, my heart is pumping so fast and hard I get dizzy, I shake like crazy, my voice cuts out, And I still can't breath 5-10 minutes afterwords. I have a presentation to do tomarrow and I'm extremely nervous about it, any tips would be highly appreciated =)
