Stage-fright is one thing, pervasive chronic anxiety is another.
I used to have frightful stage-fright when I started having to give papers or talks at scientific meetings.
Shakin' like a dog
peach-pits - as they say in Georgia . . .
Gradually this wore off; perhaps getting wiser, perhaps getting more confident in what I was talking about - perhaps realising that the people out there were no better (and maybe no worse!) than I was. Also a belief that I had something to give them in the way of information or insights that just might make a difference.
Practice, practice - go for walks and give your talk to the sheep, then shout it to the cows, then to the clouds, so that you can speak without notes and extemporise.
Pervasive chronic anxiety seems to do better with cognitive behaviour therapy than pills, so you may want to consider that. I'm glad that your nervousness, for that may be all that it is, is improving with time and treatment - that is an excellent sign.
Good luck and best wishes.
