Without text is better.
"sick with unknown illness" isn't exactly correct. It is known, just very little is known about it.
It's illness of unknown cause.
Also, it isn't exactly correct to say "No funds for research." If that were true, there would be no research. It might be correct to say, "very little public money for research."
And "no disability pensions given" isn't true. Some with ME / CFS do receive disability.
And "no health care" would certainly be false. Many doctors are providing health care.
