Welcome to the forums,
I'm very sorry your budgie is not feeling well.
From your description, it seems she is suffering from respiratory distress and in order for her to get right treatment, she needs to be properly examined by an avian vet specialist.
Until you get her an appointment, you can try to provide some relief by creating a little steam room for your budgie. You can do that by running the shower hot, placing your budgie's cage in the bathroom and closing the door.
The steam will help in opening her airways and making it easier for her to breathe.
Still, this will only give relief and will not cure the ailment, for that she needs medication.
You can keep her extra warm by covering the cage on 3 sides, if need be, you can also place a hot water bottle underneath the cage's bottom.
I'm aware it may not be easy to find a qualified professional where you live.
