When carers can't care anymore

After 16 days and a failed procedure to sort out her physical problem my mother has been discharged. It's been an interesting two weeks. But apparently she is fit to be released with daily visits from CPN. I have left her with meals for a week, yes I will be visiting during this time but bulk cooking is easier. Today was great fun, I arrived with her shopping, no answer. I rang the doorbell and her landline and mobile no answer. I rang her friend, she wasn't there. So I rang Mr B who zoomed down to come in house with our keys. Even though she is my mother I do not like to use keys to her house unless agreed in advance. I think it is rude and would hate anyone to use keys to mine. She was snoring in bed. Apparently the nurse who visited has told her she is not mental!!!! I doubt the nurse would say this but it makes her feel happy. She is not dressed, at 3pm. However she had some toast at 8am. I stayed and made her lunch and her tea. She is a shadow of her self, constantly retelling things over and over. This is not normal. I asked about the voices and noises she was hearing in hospital. She says these have stopped but she is having altered thoughts, this is clear from her discussions. I asked what the nurse said about the voices. She said the nurse never asked so she never told her. I think I need to see the nurse. Not only is my dad in permenant care now, but my mother is also disappearing and if I don't get a referral to the psychiatrist who specialises in elderly I will be screaming soon. She is however much better now she is at home. However I can't be certain if this is because she won't tell me, the drugs working or she is genuinely better. On a positive note dad is thriving. How long though will it be allowed that elderly are left to care for spouses until they reach breaking point, families can intervene but GPs should spot the signs and not ignore them. The elderly are not just regular visitors wasting your time, they are making a cry for help which GPs need to pick up on and intervene.
