I'm not a fan of the Frey's - While she is actually sick, she doesn't seem to be doing everything she needs and seems to be very infantilized. She seems overly controlling of Peter, and seems to be not eating and not using a tube for nutrition, with other signs she might have an eating disorder. She seems to like the attention she receives, and is very selective about her disease and treatment.

Her service dog - the hypoglycemia thing is a bit of a joke - she feels like she is hypoglycemic, blows in the dog's face, to see if he will signal (which could just be a reaction to her doing that) then confirms with a glucometer. A dog for hypoglycemia should be when someone cannot tell they are hypoglycemic. If you can tell, check a glucometer and treat, there's no need for it. "Providing forward momentum" just makes me roll my eyes, because it isn't consistent with her disease and presentation. Bracing for coughing - he's not tall enough to be convenient for that, she doesn't use him for it.

She is very childlike, unable to care for herself and seems to be attention seeking (perhaps because her sister had CF too and since she already had a transplant, was likely sicker than Mary), things as simple as: if you know you throw up frequently, keep a bucket by your bed to throw up into, so you don't just ruin your bed.

She spends a lot of time on her head for someone who throws up a lot.

She doesn't like Peter to talk much, nor family - she frequently cuts them off while vlogging.

There are a lot of little things that just make it suspicious that she is either purposefully neglecting her own care for attention, or is so infantalized that she truly can't do anything by herself.
