Does anyone have advice on dealing with chronic tension head and neck pain?

I have been dealing with severe tension neck and headaches for over a year straight. There has not been one day that I have been relieved. I've been to the neurologist. I've had blood tests, ct scan, and an mri. I've done physical therapy and acupuncture. Nothing seems to work. I've been on all sorts of preventatives and pain killers. I can't bend my neck down for more than a few seconds. I can't exercise at all. I can't go outside if it's too hot out. I'm always really hot. I'm always dizzy. I can't think straight half the time. My eyes hurt all the time, I can't move them too quick or too far to the sides, they are very light sensitive, they ache all the time. I have trouble sleeping. I feel so hopeless and sad. I feel like nothing will work and like my life is over. I feel so ill all the time, and just lay in bed and cry. I need advice. I wonder if anyone else knows what I'm going through and how they cope or deal with it.
