Just scared: Cancer and scared leaving my daughter behind

My name is Heather, I am 38 years old. I had surgery/diagnosed on 10/9/24 with NSCLC adenoidcarcinoma EGFR 19. Non smoker. I have had multiple lung nodules for 15 years. We followed them for a few years, but due to how young I was and no smoking history, I was told they were benign, and follow up was stopped, unless I started having symptoms. I had bad chest pain before my surgery, which is how we found the cancer. During my surgery my largest nodule was 2.3cm with Visceral Pleural Invasion. I also had 3 tiny tumors around it, but all considered primary tumors. Therefore stage2b multifocal, I did not have lymph node involvement, no lymphovascular invasion, or airspace invasion. They believe the other nodules that have been stable for 15years are atypical adenomatous Hyperplasia. I am scared beyond belief. I have a 8year old daughter who is beautiful and she is autistic that I am scared of leaving behind. Chemo was not recommended. I went straight to Tagrisso. I don’t know what I am looking for my writing this.
