I have ME/CFS and I've experienced similar disbelief from others, including doctors, since 1990.
("but you don't *look* sick ...")
I am so sorry that Long Covid patients are going through the same thing!

"People living with long COVID often feel dismissed, disbelieved, and unsupported by their health care providers, according to a new study from the University of Surrey."
I want to add that "offering psychological support instead of medical care" is not helpful. It is indeed insulting.
If you offer psychological care *in addition to* or *as part of* the overall care then that's fine. But it should never be offered *instead of* medical care.
Maybe this is a misquote by the author? I don't know, but the way it is stated here is wrong.
Psychological support can be very helpful! But it is never a substitute for other medical treatment.
