Okay, so it was a caring remark. I wonder if grabbing the ring represents your response to her caring remark. Are you aware of how you respond to her care? Does it simply feel lovely or is there any discomfort involved?

I agree with Thunder Bow that the sinkhole represents the effects of the anxiety and depression, that it speaks about the destructiveness of it and how it affects your life. Perhaps it affects the structure of your life. Are you suicidal ever? The class got out in time suggesting that the sinkhole doesn't threaten the lives of the class.
