It is very common to feel nervous when addressing a formal gathering. I too have faced this situation several times but with a few steps, one can overcome this fear unless it is so strong a feeling that you might need help.
- Tell yourself that the people you are addressing are just like you and you need not feel afraid of them.
- Dress in your best because it will give you great self confidence.
- Prepare notes beforehand and rehearse your speech well so that you will not falter.
