This is a terrible time for you. My guess is that your Mom is handling it better than you are. My mom had this crazy cancer and would find a reason to send the family away so she could have time alone. She told me more than once to take my family and shop or go somewhere and be normal. It was tough but we did it and the day she must have known she was going to die, she said she would live until all of her kids were by her side. When my oldest brother came, he was the last to arrive, she just let go after my brother prayed for her, and died. This was how she lived her life. Head on. Got you in my prayers and your Mom too.
