Hello sir , Your issue is uncommon , if there isn't any biological disorders we need to check the psychological part. You should approach a therapist who will evaluate your case history , understanding different areas which may have contributed to this condition. Please approach a psychiatrist or therapist. A physical health check up prescribed by a physician would also give a better insight.

I understand that you're facing a serious problem with your vision. But if the opthalmologists ruled out the eye problems, this calls for a thorough evaluation for other possible causes. It would be better to get a full evaluation from a Psychiatrist as the problem seems serious enough to compromise your routine and confine you indoors for the last 4 months
