I to am a Ros1 cancer fighter. I was diagnosed in 2022. I am in total understanding of your situation. Only one family member knows about my cancer, because of my wishes. I have a close net group of friends that are my prayer warriors and I am so blessed that they give me space and understand my feelings about trying to live a normal life. My side effects are not so severe as yours seem to be, because I am still very active.
I pray that you can still find joy in your day to day life, we definitely live in a new world with new options to treat our cancer. There is no one like another person taking TKI's that understands our journey. I wish you the best you can be.
