Recently I have been sick. Not horribly sick but there is something going on with my gastrointestinal system. Intellectually I know that it is probably IBS but I keep having obsessive thought that something is seriously wrong. Earlier I was seriously worried that I had colon cancer and now I have become concerned that about the possibility of pancreatic cancer. I am already seeing doctors and working of what my symptoms suggest is the issue and I know that my fears are not rational but I am extremely anxious. It is not like me to be anxious. Please help.
