It sounds as Lucha is suffering from a severe gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking her to the vet urgently, she will need to be checked first, if the vet thinks it's a simple gastrointestinal infection she will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.
