How can I get mom to be okay with moving to a group home? She's 94 with dementia.

She's lived on her own for 10 years plus, moved here from Richmond, didn't want to move here, now in a Senior apt but no assistance, I do everything and its time to do something different. She needs more care, attention, gets turned around, what day is it? who's coming to get me (we work)? sits outside at the apt all day, waiting for someone, I don't get there until 5. needs personal hygiene and reminders re wearing a Depend. She doesn't trust folks thinks everyone will steal or even the lady at the group home could rape her. WHAT? OMG...... I have prayed over this, I have searched many group homes and feel good abot this one... run by a Christian woman, plus she has 2 other group homes that are full. I got a good vibe from her. Home is very nice. We have visited, she said she would go for one week. Gee. the GH lady said not to protest, just go with that as a start. What to do? In my heart, I know its the right thing, don't want her to fall or something else happen then what? I called the church today and the minister said she would come by and talk to her, but with the dimentia, she said she could still bring it up again.....She moves Friday. I try and bring it up every day so she won't forget, then yesterday she said I never would have thought my daughter would be involved in such. Involved in what? Pls pray for me and her too. I feel sick to my stomach. I know in my heart its the right thing but I just want her to be ok with it too. Too much to ask? Anyone got any words of wisdom.
