Tizzy, hi and welcome to TP.
Please calm down. This is not to see if you are a good person doing a good job and to take your mother away, this is to see about help for you, like maybe equipment for the house, or putting you in touch with support services in your area, making an emergency plan, that sort of thing.
Usually the LAST thing they want to do, is remove someone from their home.
Take a look here:

If your mother has not had a needs assessment, or not had one recently, ask for that as well.
Caring for someone is hard work and I would advise you take all the help you can get! If you don't get help and support for your mother AND for you, you are risking your own health. This isn't a job that one person can do alone, 24/7, with no help, forever, without risk of carer's breakdown, serious illness, or worse.
You know that announcement on airplanes, about how if you are traveling with someone who needs assistance, that you should put your oxygen mask on first, and then help the other person? That's what this is like.
I am sure others will be along to reassure you and tell you about their own experiences.
I hope you will be able to get some sleep tonight, and best wishes to you and your mother.
