Body scan is clear

So I did the body scan it took about 2o min. The results soon followed. Doctor called me in and sat us down it seemed like he was making small talk and I was so scared. I looked at my scans on the screen and I swore there was cancer spread and there. However he asked how I felt and then paused and told me that he would see me in a year. I stood up in disbelief and felt like I was about to collapse. I knew that I should be grateful and I was but I knew I felt like a train had also hit me and wonder if this was how I was going to live out the rest of my life. Hypo and sick. I could not even think my mind is so slow I can hardly articulate much. My breathing is screwed up. and I got severe heartburn that won't let me sleep. Besides that I get this panick inside of me like I am going to die. I cannot explain this feeling it feels like I need air and I want to leave this body. I do not recognize it as my own. It has changed so much. I do feel disconnected from everyone even my husband. I feel he cannot truly understand what I am going through I mean no one can. I am afraid and I do not know who to turn to for comfort and to ease my anxiety. I am not so much afraid of death as I am afraid of the dying. I do not want to be afraid and in pain. well this is all for now.
