I always trick myself to do those. I'll practice by writing out everything I want to say and going through the slides but then in the hours leading up to it, purposefully distract myself until "oh hey, it's time to talk" so I don't give myself time to work myself up.Im also afraid of public speaking. My voice and body shake when I'm presenting something to a crowd, but I can and do make myself do it without too much trouble
Bees and wasps are different. Bees are cute where wasps are the a**hole.My biggest fear is bees. When I see a bee near me, I flip out and run. I have a LOT of trouble making myself stand still to spray a wasp nest.
