Having had 4 cancer diagnoses in my life, one was a metastasis in 2002, and 3 different types of cancer, the latest in October 2021, I found the anxiety can be overwhelming if you let it run wild. I learned that we must take one day at a time. Don't let your mind play havoc with your "what ifs". Deal with the present. I was given almost no chance of surviving my metastasis for more than a few years. I accepted it and did my best with the life I had left. Here it is 22 years later and I made it despite all the odds, but now have a new cancer, bladder, from all the radiation in the past. If possible take some yoga classes, meditation classes, develop your spiritual side, spend some time in nature, give yourself some quiet time to just relax and focus on the now. Sounds like hocus-pocus to some, I understand, but I learned it helped me a lot in my cancer journeys. It helped keep my mind strong. I'll be sending out healing prayers and thoughts your way.
