Step-by-step explanation:
Lyddie was upset when she received a letter from her mother because the letter informed her that her family was missing her and wanted her to come back home. This made Lyddie emotional and upset because she was torn between her desire to go home and be with her family and her commitment to work and earn money.
For example, in the letter, Lyddie's younger brother wrote that he would rather see her than do anything he knows, showing how much her family missed her. The letter also mentioned that her mother said thank you, indicating that their request was urgent and she wanted Lyddie to come home as soon as possible.
