My mom is a lot tougher than she looks. She sailed through the surgery and is on the mend. Although she's still in intensive care, she is expected to move to a regular room soon and will come home next week sometime - if everything continues to go well.
Thank you to everyone who expressed concern through comments, emails, e-cards, and phone calls. Who knows - Maybe Nexus saved my mom's life... Nexus has turned us all into fighters. Before her operation she said that she needed to survive this surgery because she wanted "to live to see NEXUS go away!"
So her new name is "Strongheart the Warrior Queen". We are so relieved that she is still with us. Of course, it would be a mistake to underestimate this itty bitty little old lady. She's my mom. :)
Thank you again!
