I watched that show with tears too. I knew she was going to see her mom, I didn't know the mom died. What a blow to Robin as she enters her health treatment. I thought she was going just to see her mom before entering.
My friend went through this same thing. she was not allowed any contact with family during it because the immunity is lowered. She came through it well. My friend's mom died during the confinement and she could not go to the funeral. This condition is a result of the chemo used for breast cancer.
Robin will be back, she is a strong person.
