I am able to understand your situation. Your mother seems to be having psychotic symptoms like suspicion, talking to herself, hostility etc. However more clarity is needed regarding her actual problem. Is it the first time she is like this? How is her sleep and food intake? Is she a diabetic, hypertensive or have any other medical problems? I would be more than happy to help you. Some counselling and if needed medical help might be needed for your mother.
Next Steps
She would benefit from a psychiatric consultation. You can directly consult with me through Practo. Online chat consultation is also available.
