What does mama find most difficult about life at the camp? ?

"Farewell to Manzanar" is a collection of memories published in 1973 by Jeanne Wakatsuki Houston and James D. Houston.

Jeane's mama find it difficult to live in the Japanese-Americans camp. 
At the camp the Japanese Americans find crowded living conditions, worst prepared food,  barracks are unfinished and dust blowing in to every crack and knothole. There is inadequate supply of warm clothing to go around; many get ill from immunizations and poorly preserved food, and they face the indignity of non-partitioned camp toilets. All these, upsets Jeanne's mother.
