Please check my Mom CT Thorax. Scans?

My mom has had a cough with mucus and chest noise for the past 3 months. We recently did a CT Thorax, and the report mentions fibrotic strands in both upper lobes, a subpleural fibrotic band in the right upper lobe, a linear fibrotic band in the left lower lobe, ground-glass opacities, and mosaic attenuation. She does not have significant breathlessness, and her oxygen levels are normal. I'm the only son for her I'm very anxious about this report i didn't sleep for the past 10 days and continuously cried. My mom is very poor from childhood she did very hard work (beedi making) to raise me. Is this a serious condition? Does this CT suggest IPF? Is this fibrosis mild, moderate, or severe? Is this condition life-threatening or likely to affect life expectancy? Please tell me 😭 We went to the pulmonologist and the doctor said it was mild and prescribed some cold medicine and inhaler only. What treatment would you recommend? Does she need regular follow-up scans? Please help me doctor 😭
