agitated happiness

 “When he held her that way, she felt so happy that it disturbed her. After he left, it would take her hours to fall asleep, and then when she woke up she would feel another onrush of agitated happiness, which was a lot like panic. She wished she could grab the happiness and mash it into a ball and hoard it and gloat over it, but she couldn't. It just ran around all over the place, disrupting everything.”
