Don't panic. Get it in your mind you will never panic in any situation. Panic, if allowed to come in, takes over. It makes you "deaf, dumb and blind."
It makes us useless to ourselves, to others, to God. You must decide right now, in the moment where there is no temptation to panic, that you won't. So when a situation comes that could bring this on, you can stop it before it takes hold of you.
Panic never helps anyone.
Panic, makes you helpless.
it accomplishes nothing.
