Has anyone suggested you might have fibromyalgia? Many of your symptoms - poor sleep, needing lots of sleep, pain, trouble concentrating, etc. really smack of fibromyalgia or FM. FM is a hypersensitivity disorder that causes widespread pain, fatigue, poor sleep, problems thinking etc. Its treated differently from most other 'pain disorder' partially because its not just a 'pain disorder' at all but a central nervous system disorder that effects many aspects of ones life. It often goes undiagnosed.   http://www.healthcentral.com/chronic-pain/fibromyalgia.html   Health Central has a good FM section. If you do end up having it there are some good support groups such as the NFA you might want to check out.   Good luck. You deserve better.
