My Grammy has stage 4 ovarian Cancer.......

Hello Everyone. I found this page by coincidence and was just coming here for a little support if that is o.k.? I did not know where else to go. My Grammy is 72 and about 2 years ago she was diagnosed with stage 3 or 4 ovarian cancer. Unfortunately it had spread to her colon and bladder as well. When she was younger she had a partial hysterectomy, and when she turned a certain age (I can't remember what that was) they told her that she didn't need to get pap smears anymore...so she stopped. About a year later she was diagnosed. I live in another state and so when my dad called to tell me I was heartbroken. She had surgery and not to long after that she had started her rounds of chemo and radiation. For a little while her cancer had shrunk and was not really doing anything so she went into remission. It came back and then she did some more rounds of chemo and radiation. I got a phone call from my sister (she quit her job to take care of my grammy) telling me that they were waiting for the hospice nurse to call back and they were going to put her on it and they did. My dad said that they were only giving her 1-2 weeks left and it has already been close to a week when they had said that. Right now she is in the hospital because I heard that she is really delusional and she is starting to become forgetful and violent. For instance my sister told me that yesterday they were visiting her and my grammy wanted to get up and go to the bathroom (but she has a catheter in) and she was insisting that she needed to get up and go, they called the nurse in and when he showed her the pee bag she hit him and said "get away from me son of a b***h". I am flying to AZ on Monday to go see her but I am scared. I am so afraid to see her like that and I am probably going to lose my composure when I do try to go. What if she passes away while I am there? I am pretty close to her as she raised me until I was about 5. I just love her so much but I know that she is just ready to go to her final resting place and be reunited with my grandpa. Thank you for listening if you got this far.
