I know you are worried about the bills but I'm worried about Cyn. Have they checked the arteries in her neck? When my mother kept being faint and actually passed out a couple of times they discovered that it was blockages in her neck.

It also might be better for Cyn's stress levels if you could have a bit of trust in the doctors? I know that the family doctor rather let her down but still... they know lots more than any of us.
