I agree with hamster, best way is to avoid head on collision with your mom and any other bad things that might come up without escaping the responsibility.

Do you love woods? Why not take a walk and try to see stuffs you never noticed.

The trick is, you see, to divert your concentration. Focus on something that draws your attention easily. Get the stuffs out of your head. When you are in the bathroom, try to see the texture and color of the wall, listen to the sound of the flowing water.

When you are not in front of your mom, the only place she is at is in your mind.

So, fill your mind with some other stuffs!!

God be with you.
