Could my headache be incurable?

[tent21]

I have been suffering from headaches from the past 3 years. Doctors haven't been able to cure me. The Doctors been given me medicine for migrain, depression, painkillers, elpilepsy. At somepoint i started getting hallucinations too, the doctor gave me Olanzapine and the hallucinations stopped. Now it is just headaches, pain is worst in the back of the head, it feels more like wounds inside the head. I have taken CT scan, lumber puncture, blood tets and they showed nothing wrong with me. Often the pain is so bad that i consider suicide as a solution to take it away. Also most of the time it hurts both in the ear and inside the head when hearing things, specialy if the sounds around me are a little louder than normal, so i go to isolation when this occurs. Just before i got these headaches i had a car accident but i wasn't injured anywhere in my body. My speed was 120km per hour when i hit the wall in a tunnel. So my doctor assumes this is the cause for my headaches and years ago he said it will wear off in time but it doesn't look like it is going to since the headaches has gotten worse. Does anyone here now what might be wrong with me? Any ideas, suggestion?
