ILD diagnosis nothing helping

I had covid in 2023 and from that time on, had energy deteriorate. Saw specialist April 2025 and have had x-rays, CT scans etc. Was put on prednisolone but started having vision problems so stopped.
Have always been an active person and have had no major health issues over the years. I have been so lucky. I am 83 years old and having problems breathing. Doctor has suggested I go on half prednisolone and he will see me in another 3 months after I have had x-rays, spirometry.
Heard that Breo inhaler may be helpful but can cause side effects.
Is there something that will help me breathe better .
I live in Melbourne Australia,
