The anxiety is a secondary symptom of the IBS. I am a naturally very happy person. I have never done the beat myself up internal monologue. The anxiety I get is always very odd and difficult to understand why I suddenly got anxious. My life has always been very easy. I always finish tests first. Writing papers and math were always easy for me. I am always the golden boy at wherever I work. I've been offered free rides to grad school for my work performance. I easily command any conversation I care to.

Anxiety, insomnia, depression. These are things that should be obviously understood as a secondary symptom of something else.
