Does anyone else worry that lack of appetite must mean they have cancer? It's all i come up with. I have been super stressed and anxious for the last three weeks about a some abdominal pain I had which has now gone. I convinced myself it must be stomach cancer. The GP tried to reassure me but it hasn't helped and I'm convinced that even though the pain has long since gone, the lack of appetite must mean something serious. I feel hungry as normal but cannot find any food which seems appealing and it's become the centre of everything - all I can think about is why don't I want to eat, it must be serious. People have told me that anxiety can cause appetite loss but I have a hard time accepting this because how do I know the cause is not some horrible cancer? My GP even ordered blood tests to reassure me, but now all I can do is panic about what they will reveal. I feel like I'm going crazy. Has anyone else lost their appetite for such a long time and assumed it was a symptom of something horrible? I've had mild health anxiety since I was a child, worse since I had my own child, but never this bad. I've usually been able to keep it under control but feel like I've lost all sense of reality this time. Please someone reply and tell me they've felt like this too!
