You really have my sympathies and I hope your mum settles and you can begin to feel less guilty soon. However, if this doesn't happen, take a look at the following website.

Guilt is a terrible thing and sometimes it never goes away, so I wanted to just check that you were aware of this type of thing. I've jumped through a few hoops recently myself, beaten myself up, and am now in a compromise situation. My peace of mind with regard to absolute safety would be greater with my mother in a home (she was in one briefly and now isn't...long story...) but HER peace of mind is better when she has independence. It's a terrible dilemma to face, and it is difficult to strike a balance between physical safety and mental contentment. How much loss of each is acceptable? And whose decision should it be? Could we forgive ourselves if our elderly parent had an accident at home? Is this actually less likely in a care home? At what cost to the person's mental state? And freedom? Am I doing this for her well-being or for my own peace of mind?
I've been there

and my decision was to take risks and let her retain independence for as long as possible, going against all advice. So far so good - but I do have to accept that an accident is possible - and I have to live with that. It will be seen as my fault for going against advice. The above option is not available where we live, but I would jump at if it was.
I hope I'm not putting doubts in your mind after a decision has been made, but I know I would have felt physically sick if mine had been in a home and there had been an option like that which was manageable, which nobody had told me about until it was too late.
I also hope this doesn't further upset you - but I reckon all these things will be flying round in your head whether or not I say this - and I just wanted to tell you that there are other options which can work if you really can't live with this one. And doctors don't always know best. x
