Upcoming Panel Discussion, need advice on how to come out of my shell

I have an upcoming artist panel talk about my artwork in front of lots of people. I’m nervous because I know I will start sweating (a lot!!!!!!) and getting shaky, heart racing, my vision will get all tunnel like and start to pulse… it’s bad. And this is kinda how I feel right now even typing this out just thinking about this panel discussion.

That being said, can you guys give me any advice on things to implement before? I still want to be myself, I just want to be more chill and make sure I’m not sweating like crazy or on the verge of passing out on stage. I know people say they take a shot to calm their nerves but I’m NOT going to do that!

Thank you guys in advance! I really appreciate it.
