Please help me save my princess whippet willow

Unfortunately this has come from no where and willow is suffering massive pain and sadness

I took her to an emergency animal hospital that told me without a ct scan they can’t help or dianose her and the total cost would be between 3/4K

unfortunately I can’t afford this with having lost my father and brother and no dealing with a marriage break up and I can’t loose my baby

if I can’t help her my only option will be sadly to end her pain

currently she has had a pain injection and has lube for her eyes to help protect them but she is weak very weak

thank you everyone so so much willow is now being seen to by professionals and getting all blood work done
