I would still watch her closely. Vomiting yellow and greenish fluid is NOT normal and indicates something very definitely going awry.

I live in California and pay what it costs to live here and pay for my all cats' vet bills myself. They are expensive, but they are lifetime commitments; I make adjustments in other areas of my budget in order to afford them the care they deserve.

"Engergy" shots? What is that? I've never heard of such a thing. Stopping eating and "loosing" (sic) weight are also not good signs. The blood tests may have come back normal (which was the case with my RB Goldie last year; she was dead from liver cancer within a few short months). Please continue to watch your cat very closely for anything that varies from her normal perky behavior. Cats are masters at masking illness and because they can't talk, we are responsible for making sure they stay healthy.
