Ok here's the deal. I am 26, female, smoker, longtime anxiety/health anxiety sufferer. My dad was diagnosed with colon cancer about 5 years ago, they found it really early, removed it and he's been fine ever since. I just found out that my second cousin who is younger than me, was recently diagnosed with colon cancer, which has now spread to her liver and she only has a few months to live. I am terrified that I have this disease and am dying. I don't know if it's IBS that I suffer from, I've been having constipation and diarrhea at the same time if that makes sense, extreme nausea, i have absolutely no appetite, and my stomach feels huge and full. Does anyone else experience this as a result of anxiety? I have a dr. appt tomorrow for a routine physical and will have my bloodwork done, etc, but I don't know if I should have this looked into further. I cannot sleep more than a few hours a night, my mind is running non stop and I just cannot get a reprieve from these feelings that my life is coming to an end. If anyone can help, please, it's much appreciated.
