@anahitam, I think I can understand and sympathize with you and your Dad with this terrible year of health issues. It sounds like his immune system took a beating fighting Covid and allowed the rest to take hold. I cared for my father who was diagnosed with oral SCC at the age of 70. Despite radical surgery, chemo and radiation that was available back then, he died in 1993. He was not a positive person, and felt that his cancer was relentless and unstoppable, and likely his history of alcoholism and smoking worsened his prognosis. Now, 30 years later, there are so many more options for treatment, so much more knowledge about cancer, that there are many reasons to stay positive in a cancer battle. In 10 years of dealing with H&N metastatic SCC myself, I have had many moments of panic and anxiety. It can be so hard to stay positive, but in the end I really think your attitude helps in the cancer battle. After mentally addressing all the worst scenarios, allow yourself to then consider and picture the desired result, with a successful treatment and continued life with your family. For me, time spent outside in nature is the best medicine to be "in the moment" , reduce stress, and refresh my optimism. Think of the medical staff as members of your team, all fighting toward the goal of prolonged life for your Dad. Seeing him weak and in pain is so very hard, but your strength and support can be his rock to help him get through this. Keep educating yourself about options and above all, try to find your optimism again and hang onto it. You both need that attitude to get through this. I found help with positivity with a book called Radical Remission by Kelly Turner. I wish you both good luck and skilled doctors and a good path report. And remember that there are more treatments available as more information is gained. If need be, a second or third opinion can open more doors. Be strong and God Bless.
