'Surrendering' & 'Being' the anxiety/fear.

Lately I've read a bunch of Eckhart Tolle and Alan Watts and both of them, several times, particularly in Alan Watts' Wisdom of Insecurity and Tolles Power of Now mention that to conquer anxiety you just be so present that you BECOME the anxiety and completely surrender to it.

How can I BE the anxiety? How can I surrender? I've been meditating daily for 12 months this month.

Thanks in advance.

Peace.
