1. YOU HAVE A NEGATIVE OUTLOOK ON LIFE IN GENERAL.

2. YOU HAVE A LACK OF CONCENTRATION.

Both of these options could be directly related to not getting enough sleep. Not getting enough sleep can negatively impact a person's mood, leading to a negative outlook on life. It can also affect cognitive function, including concentration and focus.

The other two options, having supportive relationships and a strong sense of purpose, are not directly related to not getting enough sleep. They can certainly be beneficial for overall well-being and can potentially indirectly impact sleep quality, but they are not direct effects of sleep deprivation.
