Calm is not passivity; it is controlled access to your full intelligence.

Calm gets mistaken for not caring or not acting, when it is the state in which your abilities are actually available. Under stress, the more sophisticated parts of your thinking drop out and you are left with reflexes. Composure is what keeps the whole of your intelligence online, which matters most exactly when the situation is hardest.

If you have been treating your agitation as evidence of how seriously you take something, consider that it may be reducing what you can bring. Settle first, then act. The action will be better and probably faster.
