The care is there, but fear I've not the discernment or knowledge to match. You ARE doing a lot to cope with the current pain. I'm sorry the results are not optimal.
Sleep is great, but if it isn't genuinely
refreshing sleep then it helps little. Have you ever had a sleep study? Unfortunately, in my experience, the folks running sleep studies almost always look exclusively for signs of sleep apnea. If they find it, they say, "Ah-ha! there's the problem." If they don't find it, they throw up their hands in resignation. Too few look beyond to the nature of your "sleep architecture."
The aphasia is also a concern...
