How do you keep fighting stage 4 lung cancer when treatment gets tough?

This is a message for all who are currently battling this scourge of a disease! Even in your darkest moments of despair, keep fighting! I know first hand in my battle with the constant pain, nausea and fatigue. I did a course of radiation and then started chemotherapy, once that was done I started my current treatment of infusions of Keytruda every three weeks. This has been no picnic. I was unable to eat hardly anything at all. Eveything tasted horrible and I was getting dehydrated because I didn't even want water. Before I could even get my treatments they had to give me fluids first. I lost about 50 lbs. And i wasn't a large man to begin with, so i definatley looked like your typical cancer patient you would see portrayed on television, minus the hair loss.My blood pressure was low from the dehydration, which caused me to pass out a couple of times and I fell. When it was hot outside in the summer I was freezing. When others were wearing shorts, I was in a sweatshirt and jeans, air conditioning was torture. There was also this constant feeling in my legs that made me have the urge to move them. I ended up in the hospital twice due to a bowel obstruction due to pain meds. And pneumonia from aspirating vomit. Hang on, there is hope now! Treatments are so much better than they were in my parents generation! October 31st 2024 I was diagnosed with stage 4 lung cancer, a pancoast tumor on the upper lobe of my left lung that was pressing on the bundle of nerves that run through your shoulder and causing excruciating pain and making my left eye droop. It had spread to my left adrenal gland. I have been out of work and on disability since then, but on December 22nd 2025 I had my latest PET scan performed and it showed no cancer in my lung, adrenal gland or elsewhere in my body! I meet with my oncologist this Monday to go over the results and find out the next steps. I still have numbness that runs down my arm and into my hand. I have been told that it may or not be permanent. So, you see there is a reason we have to keep fighting. I hope this may help someone who is about ready to give up.
