Difficult English

운동을 마치고 집에 오는 길에,
I was on the way to home after an exercise.

어떤 여자분이 쪼그려 앉아서 강 옆 난간을 붙잡고 흐느끼고 있었다.
A girl was sitting down and crying nearby river.


그래서 '원래 세상은 X같은 거야', '그러니 강해져서 열씸히 살어'.
라고 말해주고 싶었는데,
So, I'd like to tell her 'The world is actually XXX', 'So, you should be stronger.'

'원래 세상은 X같은 거야' 를 영어로 그럴싸하게 말하려면 어떻게 해야하는 건가.
However, I didn't know to how to say in English, 'The world is actually XXX'.


The world is actually in a dumb.
The world is actually a garbage.
The world is actually crucial.
The world is actually a tragedy.
The world is actually sad.
...
A human life is actually bad.
A human life is actually in a dumb.
A human life actually sucks.
...

그래서 그냥 와버렸다. 껄껄.
At last, I just came back home.

좀 알려주세요. :)
Please let me know how I can say that. :)
