Oh my, I send many hugs and prayers sweetie for a good outcome. So very sorry to hear about the loss of your dear Dad , and now your Mom being so sick. I can imagine how frightened you are and how much your heart is aching, but please try to keep the faith. It's a good sign she is responsive, she knows you are there, so perhaps surround her with positive vibes and all the things she loves, talk, read, pray with her and play her favorite music. Take care of yourself thru this difficult time.
