So why did she feel such a deep sense of loss?

We all now feel that you are really one of us in a deeper sense.

I might experience not only fear but also a deep sense of rest.

I had a deep and profound sense of having made a wrong choice.

Having made the decision to act Gary also had a deep sense of peace.

What he has lost is its deeper sense of loss.

"They have a deep natural sense of how plants grow."

He had a deep sense of identity with living things.

"There was a deep sense of commitment to the cause."

It left me (and I am sure many others here today) with a deep sense of personal loss.
