How do I do this?

I'll spare y'all all the details, but it's become apparent that it's time for my mom to go to a hospice. I have medical power of attorney, so getting her in there is not an issue. The thing is, my mom is still convinced that she is going to get well, that the chemo will once again put her into remission. Now I have to go to her and tell her that it's time for her to give up her whole life, move into a hospice, and prepare to die. How do I do that? It's not so much the words, but how do I DO that? I called my sister, and she just doesn't get it. You would think, I would think, she would say she would come home and tell my mom with me, but she didn't say that. She said she would call and tell my mom. Hearing this is going to be devastating enough, but on the PHONE? I can't even believe my sister suggested that. I have a call in to my mom's doctor's office, and after I talk to the nurse about options--Hospice vs. home hospice--I'll update y'all. The nurse told me yesterday that it was time to talk to my mom about this, and I think I was just in shock and couldn't think about it. But because of everything that's happened since that phone call, it's become clear that I have to do this.

I have already talked to a very good local Christian hospice. No one--not the director of nursing at the hospice, not the nurse at my mom's doctor's office--has really offered me any guidance in talking to my mom. The director of nursing at the hospice did recommend home hospice for now, but of course, she hasn't seen my mom, etc, and when I talked to the nurse at the oncologist's office today, she seemed to think home hospice might not be the best option. She just said she would talk to the doctor and call me back, which she did call me back, but I missed her call, so I'll call her in the morning.
I just don't want to be premature in putting her in inpatient hospice, but I don't want her to be alone at her house and suffering, either. I have no clue what is best, and so I need both guidance and some idea how to break this to her.
The nurse at the oncologist's office did say that she thought Dr. K would help me talk to my mom about all this.

Heather, I have thought about you a lot since things have gotten so bad with my mom. I don't know if I was a member when your mom passed away or if I just visited back then. I do remember reading your posts, though, when she became so, so sick, and I remember how hard it was for you. I am sorry you went through that.
One of my concerns about home hospice is that my mom lives alone, so I don't know how long that option will be practical for her. If my dad were still alive or if she lived with us or someone else, I could see that continuing for a while. This particular hospice operates on donations and is free to patients and their families. I don't know if they offer around the clock care or not, and my mom can't afford to pay for it and neither can we. She is on medicaid, so I also don't know if medicaid will cover any part of at home care if we hired someone to come in.
I have thought about it a lot, and I do think her doctor should share in this task with me. He's the one who is in charge of her healthcare, and they have a great relationship. He tried to tell her that her time was limited a couple of weeks ago, but she didn't listen. I know this because she still says, "When Travis gets older . . ." or "I hope this chemo cures me" or "When I get well . . ." But if he sits her down and tells her to listen, she will. I just hate that she has to go through this. As crazy as she makes me, and as awful as she can be to me, she is still my mom, and you know, Emily just loves her so much. It's going to break her heart when we lose my mom.

OMGosh, Heather, I am about to bawl! I was okay until I got to the part about the Powerpoint and about Tessa watching it. Thank you so much for the support and suggestions.
Oh, my mom doesn't look like herself at all. I thought she looked bad last year, until I saw a picture of her and Emily from a trip we took just over a year ago. She looked great then compared to now. It's unbelievable how far downhill she has gone.
I was never so thankful for Emily's Christian preschool and for the time we have spent in church as I was when Kyle's dad died this time last year. Emily was very close to him, and so it made it a little easier to explain his death because she knows about Jesus and heaven. She was younger then, so I am sure that helped. I am not sure how she will handle it this time. I think we will go to the library and see if we can find books like the ones you found for Tessa. It will definitely help.
The nurse at my mom's oncologist's office called today and said that her doctor is going to talk to her about hospice when we go in to see him on Wednesday. I am relieved that he is going to help with this, but at the same time it is so sad.

Here in Georgia, hospice means that the patient has limited life expectancy, and the general rule is the patient has six months or less to live.
Thanks, Abby, for the book recommendation. I am going to see if I can find it tomorrow while we are at the mall.
