How does anne frank cope with her depression in the annex? how do the other members deal with stress and anxiety?

Anne Frank helped cope with her depression by writing in her diary. This diary was published by a family member after her death in a concentration camp in WWII. Other habitants of the annex tended to quarrel often, so she tried to lighten the mood and make peace. As for the other members of the annex, most of what we know from them is in Anne's diary.
