@Jeremy Sullivan59,
If someone is currently hospitalized, they're likely under intensive treatment, and if visits are causing irritation, you shouldn't force them... Patients in a clinical setting often start seeing improvement fairly quickly due to the medication, which helps them gain insight into their condition and makes visitors less bothersome. It seems like right now she might be feeling defensive, perhaps even blaming those close to her for her hospitalization...
Regardless of whether she’s accepting visitors at this moment, it would be wise to speak with her attending physician. They can provide updates on her recovery and offer guidance on how to support her and manage her symptoms once she's discharged. Having a supportive family environment is vital, especially when it comes to medication adherence...
If a patient is uncooperative or struggles to stay consistent with their daily meds, there are long-acting injectable options available. Depending on the psychiatrist's recommendation, these can sometimes be administered through community health services... It might be worth asking the doctor about such options.
When someone is in an acute state, such as during psychosis, it isn't helpful to argue or insist that their perception of reality is wrong. To them, it feels just as real as yours does, and pushing back can cause them to withdraw and lose trust... On the other hand, you shouldn't validate the delusions either. The best course of action is getting them to psychiatric emergency services. Once the symptoms begin to subside, you can gently challenge those perceptions. It’s highly individual, though, so please consult with her medical team...
