Actually i got accidently hit in my head by an iron rod very hard nearly 5 months ago. I became unconscious for few seconds and then i back to normal after 4-5 minutes. Then i searched in google about head injury and there it is written as " People who get head injury, should avoid sleep because if they sleep then they might go into coma and all etc etc.So , I have got a fear to sleep and being unable to sleep for nearly 2 months.So I decided to do a ct scan of brain in order to check if everything is all right. The report is normal.The doctor said that I am okay. But, since i was having fear to sleep for about 2 months so it became a habit and despite of doctors being telling me that your brain is ok ......I am unable to sleep due to the fear of dying in coma.So, now also I am unable to sleep due to this fear and that is why it is affecting my mental as well as physical health.My doctor told me that it is a part of ocd.Does it is really ocd? Please help me out...I am helpless.
