My mother aged 62 is suffering from daily panic attacks, and was diagnosed with depression since 2014 december.She was under aloepathic treatment under Nimhans Bangalore and recovered within a year. But again from 2016 december same symptoms are showing. It became worse since 2017 dec.In dec 2017 she went under ayurvedic treatment, was recovering bt unfollowed after the first 20 days medication course was complete.In jan 2018 she is having regular panic attacks, followed my loss of appetite, shivering, no sleep at night, always crying during panic attacks,fear of everything. Due to family issues she was going into depression and now the things are becoming worse with time. In deep sleep at night she wakes up suddenly and her panic starts and she cries, it becomes unmanageable, IT IS HAPPENING ONLY IN WINTERS EVERY YEAR. She had taken anti depression pills, bt after she recovered she had to stop as adviced by her doctor from Nimhans. kindly help how she can be completely cured from this
