That weird mix of excitement and dread before my first art show

I've been prepping for my very first local art show for months now, and as the opening day gets closer, I’m feeling this strange cocktail of excitement and dread that I didn’t expect. I usually get a bit nervous before events, but this time it’s more intense and kinda paralyzing. I’ve done everything I can think of - finalized my pieces, rehearsed my little intro speech, even planned my outfit - but my mind keeps spiraling into “what if no one likes my work” or “what if I freeze when someone talks to me.” It’s been about three weeks since the nerves really kicked in, and it’s starting to affect my sleep and focus on finishing last-minute details. I want to enjoy this milestone and connect with folks without feeling overwhelmed. Has anyone else faced this jittery mix before a big creative event? How did you calm yourself down or keep the excitement from turning into a stress spiral? Also, any tips for handling conversations smoothly when you’re feeling on edge would be a lifesaver!
