I think everyone has the solution that works for stage fright. But it is stage freight based on their own experience. For me it is always, find the friendly face in the audience and perform for that person, then the person sitting next to them and so on until I am performing for the room.

It also helps me if I meet people in the audience while I am setting up and if I am using a PA have them around for the mic checks. I am sure I can sort out the psychobabble as to why this works for me but it's late and I have silver to polish.

My sympathies, I won't wish you luck as this will pass.
