Now, let's notice some idioms that used to express sadness in this passage below:
Dear, Nany
Hope all goes well with you. Unfortunately, everyone here is out of sorts. Beth is down in the dumps because she doesn't like her teacher this year. I've told her that it's not the end of the world and that she'd better just grin and bear it. But I think she likes being a misery guts and so she complains about him every night. Suzan is also suffering from sour grapes because I got the role in the school play that she wanted. This puts a damper on every meal, so I am really looking forward to staying with you at the weekend.
Love,
Katherine

Explaination :
Out of sorts = slightly unhappy or slightly ill
Down in the dumps = unhappy (informal)
It's not the end of the world = what has happened won't cause any serious problems
Just grin and bear it = accept a situation you don't like because you can't change it
A misery guts = someone who complains all the time and is never happy (very informal)
Sour grapes = being jealous about something that you can't have
Puts a damper = stop an occasion from being enjoyable
