My mom and sister laid there like they were frozen in fear.
Were you not scared as well?
No, I was just too tired from all my work to even react to this and help them out.
It is difficult to be able to help somebody when you are so fatigued but you should try to comfort others when they are scared. That way you can comfort each other and help each other out.
I know, when I have more energy I'll console them.
That is good to hear. Your mom and sister will appreciate the kind words and it will make them feel safe again.
