Posting here mainly for traffic as I don't really have anyone else that I can speak to.
My dear nan is dying slowly and I need advice on how to try and attempt to mentally prepare for her death. We are not sure how long she has left but we know she is very ill and is deteriorating fast.
For a backstory, she is now 88. She suffered a massive stroke at 71 and wasn't expected to survive. She defeated the odds and lived but was left in a wheelchair, with her right side no longer functioning and her speech and memory affected.
Since the stroke she lived a fairly healthy life and had no physical illnesses and even outlived my grandfather who was younger than her and passed almost 10 years ago.
Anyway, last year in October we found out she had breast cancer. This isn't the first time she has had cancer as she had cancer of the bladder in the 90s but managed to defeat it.
Nan refused all treatment last year due to her age and just wanted to stay at home. Since then she has gotten worse rapidly but more so in the last couple of days. She no longer eats, is throwing up and is bleeding from the bottom (the doctors believe the cancer has spread) and this is probably likely as she has not gone through any treatment. They also think she has been suffering mini stroke attacks as she will have periods where she is dizzy, confused and has difficulty speaking.
I know death is inevitable but I'm really torn up about the prospect of losing her. I have always been so close to her and she's been my second mother in a sense, I think the world of her and it is killing me to see her suffer.
I have dealt with death and grief before when I was 14 - I lost my granddad, stepmother and other nan in the same year. At the time I was young and blocked everything out, it was only when I was about 17 that I started to become really depressed and start the grieving process.
Now that I am older I am worried about how I am going to deal with my Nan passing.
I'm sorry the post is long but I had to get it off my chest. And I hope there is somebody out there who can help me see things differently right now 
Thank you..
