Hello doctor. Last December one of my friend committed suicide in my room. We were room mates & came to Kolkata for studying purpose. After 5 days of this incident every mid night I got some unconscious situation such like anxiety, sleeping paralysis etc. It's really horrible. For few day it was stopped. But since last 1 week it is began to start. Please doctor help me. I can't understand what should I do. I had visited a doctor's clinic, he suggested me a medicine, something related to heart. I do not recall the name currently. But was not worked at all. Please doctor. Help me.
