Answer:
Lyddie is happy, she was not happy before Rachel arrived.
Step-by-step explanation:
The text shows in the question above it presents Lyddie's life as dry and lifeless, but that was modified by Rachel, who provided a change in this bad environment, like water in the desert.
With that, we can affirm that Lyddie's life was sad, boring and that she had no happiness until Rachel's arrival, who managed to change all that and make life happier, more enjoyable and lighter. Rachel brought vividness to Lyddie and a desire to celebrate life.
