“I can’t get enough sleep” is not a problem; it is a potential cause (or perhaps the result) of a problem. To clarify your thinking, try to identify the bad outcome first; e.g., “I am performing poorly in my job.” Not sleeping enough may be the cause of that problem, or the cause may be something else–but in order to determine that, you need to know exactly what the problem is.
“我睡不够”不是问题；它是问题的潜在原因（或者可能是结果）。为了澄清你的想法，首先尝试找出不好的结果；例如，“我的工作表现不佳。”睡眠不足可能是导致该问题的原因，也可能是其他原因——但为了确定这一点，你需要确切地知道问题是什么。
