I hate myself for googling

Every week I’m convinced that i have some sort of cancer. My blood test showed every thing was fine with my blood cells except that i am borderline anaemic and had a b12 deficiency. I have started supplementing and see good results. I still cant get this cancer thought out of my mind, i miss my life before i googled stuff and keep thinking that even a simple flu is lung cancer. I want this to stop, its consuming me :(
