It takes time and practice to get on the stage to officiate at the wedding and overcome psychological panic. Maybe what you lack is this opportunity to exercise. You might as well find an opportunity and regard it as a breakthrough for yourself. Pay more attention to talking in front of people before officiating at the wedding. It's inevitable to be nervous at first, but it's not so uncomfortable after a few times. It is good to be familiar with things.

There is also the preparatory work that must be done. Instead of staying up all night, it is better to focus on how to speak wonderful content. While enriching yourself, your mentality will naturally be flat. You must be very familiar with what you are presiding over, just like reciting ancient poems. This way, when you feel nervous and your brain is blank, you won't be embarrassed because you have nothing to say. If the content is substantial, you won't feel embarrassed.

Try to enjoy the process on the stage and watch everyone's expression deeply moved by what you express. This moment is the moment when you reap the fruits.
