How do you cope with lung cancer chemo side effects and talk to family about pro...

Hello. I was diagnosed with nslc lung cancer T3No stage IIb in July of 2025. I have had my left lower lobe removed and I'm now on my 4 treatment of chemotherapy (Cisplatin/Pemetrexed). The chemo has completely kicked my butt. I'm tired all the time, can't concentrate, mouth sores and dry eyes to name a few effects. I'm trying to cope with all of this and struggling mentally. Hard to talk to my wife and kids as they don't understand how I have been feeling and that makes me feel small at home. My last MRI showed an anomaly in my brain and my doctor will check after my final chemotherapy on December 30. I'm trying to come to grips with how to have a conversation with my family about my potential survival and my potential death. I'm a pragmatic person and I'm trying to wrap my mind around all of this but it is very difficult. I feel all alone a lot of times. I try to stay positive etc but I also have to be a realist. Anyone have any suggestions on coping with it all? Thank you and happy holidays to all. Be strong and positive.
