Yooo this might be an embarrassing post, but how do I go into a martial arts dojo while having anxiety?

Yooo I’m currently 20 years old so this is an embarrassing question, but how did you go into your first martial arts dojo? I really want to try out this Muay Thai dojo this year, but for some reason I’m really anxious to just go in and check it out. Do any of yall have any stories on how you did your first class? Any advice?
