sleepy yet sleepless for 13 years- please help!

hello all,
I'm 36, female, have had post-flu M.E./C.F.S. since 2007 and fibromyalgia since 2008. I was working as a doctor at the time of onset doing 80-hour weeks at the hospital with night shifts so was sleep-deprived all the years that I worked. I resigned in 2010 and am still suffering from severe insomnia where i only sleep for 4 hours per night(cortisol spikes at night awaken me) and then can't fall asleep once I awaken. The whole day after I feel overwhelmingly sleepy as if "drunk" or "drugged"/intoxicated. This excessive daytime sleepiness is so debilitating that even typing this feels like a monumental task.
Ironically as sleepy as I am, I can't fall asleep throughout the day at all.

Have had an emotionally, verbally and physically abusive childhood.

I've tried a plethora of remedies prescribed by professional homeopaths from the plant and mineral category. None of them helped except gelsemium temporarily and that too not for the insomnia.

Recently I'm being treated with sea remedies that have helped with symptoms like pain, fatigue, hair loss for which I'm grateful but none have even so much as touched the insomnia. The sleepiness is only marginally improved.
I've tried conchiolinum, acanthaster planci and i'm currently on anthopleura xanthogrammica for a week but it hasn't done anything so far.

Please let me know if anyone has any idea/questions which may help resolve my more than a decade long issue.

thank you.
