I know t can be tough understand whats going on with your wife But , you seem to be taking good care of her. Was she in therapy while takings meds?
Next Steps
You must take her to a Psychotherapist. A combination of Medication and therapy works better than only medication or therapy.

You can go for Online Video Counselling and/or Face to face wth someone in Singapore. In any case, get in touch if you can't find a trained therapist near you, well help you find one
