Six tables all wave at once. You still handle them one at a time. Overwhelm is just a line in disguise.

Feeling swamped usually comes from looking at everything at once, when you were only ever going to do one thing at a time anyway. Six demands arriving together is not six times harder. It is a queue, and the panic comes from the picture rather than the work. Putting things in an order turns the mass back into tasks.

Write the queue down next time this hits. Pick the order yourself, fastest or most urgent first, and tell the others you will be with them shortly. Then do number one properly without looking at number six.
