是的，这个句子有问题。be 的进行时态通常连用动态形容词（表示临时或暂时情况，且多数情况下含有“故意为之”的意味），而网友句中的 depressed 表示人的内心感觉（表静态）。请体会下面be用于进行时态的句子：

He was being lazy. 他在发懒。

She was being deliberately evasive. 她在故意推脱。

He was being so kind and tender. 他显得非常善良亲切。

He was being selfish and greedy. 他当时既自私又贪楚。

Her only mistake was being too generous. 她唯一的错就是显得太慷慨了。

The taxi driver was being very unhelpful. 那个出租车司机不肯帮忙。

She was being absurd—and imagining things. 她可是不讲理了——尽乱猜想。

有时 be的进行时态也连用名词（可视为名词前省略了一个动态形容词或本身隐含有一个动态形容词）：

Your brother was being a (silly) fool yesterday. 你兄弟昨天真蠢。

Jennifer was being such a pill today. 珍妮佛今天真烦人。

The man was being a positive embarrassment. 这位男士极为尴尬。

Her husband was being a real jerk about the divorce. 在离婚这件理上，她丈夫是个大混蛋。

The dog was being a nuisance, so we shut him out. 这条狗当时很讨厌，所以我们把它关在外面。
