7 months old badgie, but it regurgitate the food and she is often

Hi,
I need your help regarding my 7 months old badgie. This past two weeks she regurgitate the food, she is sleeping most of the day and is puffed most of the time. Droppings is OK. She’s not grooming herself well around the vent area (the area around her cloaca). The partner is trying to entertain her, but she is not so interested in him at the moment.

Please help….in my country Veterinary don’t know how to help.

I don’t wnat her to die, she is to young.
