You are right to be concerned. These are unusual behaviors and may suggest psychosis. An evaluation is required. You should encourage her to consult her physician. Perhaps accompany her to the appointment. She may be reluctant but going with her could ease her fears.
Once at the doctor’s office, report your concerns. Your observations will be tremendously helpful. As you mentioned, she might have a sense that something is wrong but may be frightened to pursue it further. Thus, it’s important to report your observations to her treating physician.
If psychosis is present, generally the symptoms worsen without treatment. The sooner her symptoms are treated, the quicker this problem can be remedied. Time is of the essence.
You should also inform her doctor that she has stopped her depression medicine. She should not have stopped it on her own as there are negative side effects that can arise from doing so. The more information they have about her condition, the easier it will be to treat it accordingly. Good luck with your efforts. Please take care.
