Page eight, why is Edna crying? What’s the best word from the text to describe what she is feeling?

From the text:

She could not have told why she was crying. Such experiences as the foregoing were not uncommon in her married life. They seemed never before to have weighed much against the abundance of her husband’s kindness and a uniform devotion which had come to be tacit and self-understood.

An indescribable oppression, which seemed to generate in some unfamiliar part of her consciousness, filled her whole being with a vague anguish. It was like a shadow, like a mist passing across her soul’s summer day. It was strange and unfamiliar; it was a mood. She did not sit there inwardly upbraiding her husband, lamenting at Fate, which had directed her footsteps to the path which they had taken. She was just having a good cry all to herself.
