I can definitely relate.
Before I start telling my story I should say that I have been recently diagnosed with a carcinophobia!
A few weeks ago I had a cold. A normal cold I would say. Except with my anxiety, I was worried that I got Leukemia or Lymphoma because one of my tosils was bigger than the other. After having a panic attack I checked my whole body for enlarged lympho nodes. And except for the two at the top of my neck, normally swollen during a cold, I found no lymph node bigger than a rice. That did not stop me from stating my concern to my doctor, who assured me that my tonsils, although irritated because of the cold, are NOT considered enlarged, and even though one is bigger than the other, it is no cause of concern and might just be the assymetry of the body.
During the cold that lasted two weeks, I lost 2-4 kgs, which might have been due to the fact that I was not eating (I live alone). I was also suffering from what thought was night sweats, when I would wake up sweating, but that stopped when my cold and fever were gone, and when I turned off the heater that is located less than a meter away from my bed.
Am I crazy for still having my fears? Am I crazy that I still checking my body every day? Am I crazy that I am afraid of my body?
