English Idiom to get one down

Can you explain to me the Idiom Get myself down or get you down. BJ

Hi Bj

GET ONE DOWN means to make one tired and unhappy

For example, With all the noise and everyone getting angry it just gets you down after a time.

Another example is "He had to stop work, because the problems and difficulties of the job got him down after a time"

Hope thi answers your question BJ. Good luck!!!!
