Hey @Mippy, thank you for sharing your experiences about your mother with the community!
I sounds like you and your family are going through a tough time with your mother and her episodes. It's heartwarming to hear that you and your family are supporting her and that you are reaching out for support with your peers. It can be really hard and you are being brave and courageous being vulnerable here on the Forums.
I can understand what your mother is going through as I have a diagnosis of schizophrenia and had similar delusions in my psychotic episodes. It's interesting that your mother stopped her medication a year ago and she is now having her first episode in 20 years. Medications for schizophrenia can help people with their symptoms but not always and it is a choice an individual can make whether they wish to take them or not.
With delusions it's very challenging, near impossible to change soemone's beliefs in thier delusions. Medications may help and they may take time to work after stopping them for a year but I hear what you are saying about the GP and privacy. Having a conversation with you mother and you may have to repeat the same message if she doesn't want to hear it. May help guide her to accept treatment and support if she accpeted her diagnosis in the past and can see that symptoms have become present again.
I understand that you don't want to break her trust in supporting her and you are trying to balance this while seeking support for her. There are some options that you might like to consider but might make it challenging to break her trust in the short term. But knowing that long term treatment is what may support her and to hopefully prevent symptoms from becoming more severe or long lasting.
Crisis and Assessment Treatment Teams (CATT) are able to come to your home and make an assessment of you mother and access whether she needs urgent care in a hospital. This may or may not result in her being admitted to a mental health ward but is an option to get her the treatment she needs if that's what is accessed. I know this may not be what you want for your mother but consider the distress that she is experiencing with her delusions and in her episodes. Even though you may know that they are not reality, they are her reality and the feelings and emotions she experiences are real. I will pop some links below for you to take a look at:
If you or someone in you family were the legal guidian for you mother you may be able to support her more with her treatment team. This may be more of a long term process rather than help in this immediate situation. But could be something to consider if your mother is not willing to engage with doctors about her symptoms.
I have put this here as something to consider and you may already be aware of these options. From my experience though the love and support from families is the most supportive thing a person with schizophrenia can have. I probally don't need to encourage you to continue to support her and show her that you love her no matter what. I'm sure she really finds it helpful even if she doesn't seem to show it or at times due to her symptoms. It made such big difference to my recovery!
