Here are three brief excerpts from an English lesson I have found recently in the Internet. Would you be kind enough to tell me whether the expressions in bold are interpreted properly?
“Some people are depressed all the time. They have a medical condition and need to see a doctor.”
a medical condition is a general term used to describe an observation made that can have an impact on the health of an individual.
Less commonly, the term “medical condition” is used to describe the general medical state though this usage can create unnecessary ambiguity.
“He was really depressed because he’d just found out that he failed his Math class. Because of that, he wouldn’t be able to graduate until the following year. His mood was really negative and he saw it as a wasted year.“
his mood was really negative = he was really under the weather, he was really down in the mouth
“I told him that although it’s annoying, there’s no point in dwelling on it. The past is the past.”
there’s no point in = there’s no sense of
dwell = to fasten one's attention, as in: kept dwelling on what went wrong; thinking about a situation over and over again.
Thank you for your efforts.
