My sister takes Valium (7 a day) and codeine every day and has done for years. She has supposedly FND but that has never been confirmed. She’s convinced she’s had a stroke. No one has really confirmed this and feels she is losing her sight. I’m more worried that meds are causing all this. She takes Parkinson’s meds too for tremors. Could do with some advice on how to continue a relationship with her. She’s hysterical on the phone to me most days about something or other. Sees some sort of Dr regularly. Help!
