Thank you to everyone who has responded so far!
I have a brain disease called Mal de Debarquement which causes constant sea sickness.
It's easier to just say it's "vertigo". 
One friend suggested that I might try a convent since I can offer payment.
Thoughts?
As I understand it, (not very well, mind you) this Mal de Debarquement means basically sea sickness and you haven't got your landlegs yet, and this is ongoing. Very distressing. It is not so much a brain disease but a problem of the inner ear, (vestibular) affecting balance and so many other side issues.
A few months ago I watched a panel of natural therapists explaining this and similar diseases of the ear. I wish I could find it. I will try.
Do not give hope of improvement or even a solution. I will pray for you.
