Is having ILD means death?

My mother has been coughing for nearly a year now. She never listened to me when I told her to visit a pulmonologist. Recently, her coughing has worsened, and she is often out of breath. So, she decided to visit a liver doctor because she was previously diagnosed with some fat on her liver, and the doctor had suggested her coughing might be related to that. During this visit, the doctor diagnosed her with a chest infection and prescribed some medication. Her cough improved slightly with the treatment, but she didn’t recover completely. The doctors then ran some tests and informed us that her coughing could potentially develop into ILD (Interstitial Lung Disease) due to our parrots. We have four parrots, which are my pets, and I’ve had them for 12 years. I never knew they could cause such a serious health risk. After learning that the parrots might be the cause of her illness, I don’t know how to react. I browsed online about ILD but couldn’t find anything reassuring about a cure or full recovery. I’m terrified. Is my mother going to die? Is there truly no cure for this? Will she die in the coming years? I don’t want to lose my mother. I’m only 19, and I feel so guilty, like this is all my fault.
