@silvergirl29, that's a lot. I can imagine you miss your mom as you face your diagnosis. It sounds like she was someone who not only knew your struggles and triumphs, but shared your humor and ability to laugh no matter what life throws at you.

Let me first see if I've got your current diagnosis straight. Recent screening (finally) after years of suspicious symptoms, 8 lung nodules have been found on your lungs. This coming Friday you are scheduled to have a robotic bronchoscopy. Have I got that right?

You asked "Any practical suggestions on what I should do?" I think the answers in this older discussion will put your mind at ease. @lls8000 might have more tips to share.

I know you also miss your mom's organization skills. I wonder if you could try to channel your inner mom and start a binder to organize the health journey. I say a binder, but you could use a folder on your phone instead if electronic record keeping is more your style. Keep tracks of doctor's names, contact information, tests and test results, blank page for questions as they pop up.

It sounds daunting, but could help. Do you have a place where you jot down questions as they come up? How are you doing today?
