求翻译：有时候突然就心情很低落，不想说话也不想动。 朋友问起，也不知道该怎样回答。 也许是因为突然听见的一句话，也许是看见某个物体联想到了什么，也许什么都不是，很多事情不需要理由，也没有理由。是什么意思？

Sometimes suddenly feeling very depressed, do not want to talk do not want to move. A friend asked, did not know how to answer. Perhaps it is because suddenly heard a word, perhaps to see an object and think of what, maybe nothing, a lot of things without reason, there is no reason to.

Sometimes the mood suddenly very low levels, did not want to speak and I do not want to move. My friends asked, and do not know the answer. Perhaps it's because suddenly heard the words, and perhaps saw an object with what I thought, perhaps what is not, a lot of things do not need to be justified,
