No time to be a mother

Lately, when i come home from school my mother is not home. She is not cooking meals or cleaning the house lately too. It might sound normal to you, but as conversative Muslims in our culture it seems odd. I wonder whats wrong with her. Last we spoke she said she was gonna take care of my bully problem. 

She said she will speak to my bully to make sure he wont hit me up everyday on the way to school. Now that i think of it, she acted strange ever since. What is going on?
