I didn't mean that last post the way it just came out....oh dear
You have done and are doing your best and a brilliant job caring for your mum, but there is more care needed than one person, you, can give and so you have handed 'that' care over.
You've not abandoned her, I think you have done a good thing getting mum 'extra' care. You are still caring for her and have tried to get her what she needs to be safe and well because you care and love your mum. X
