Don't do that; For starters, being a programmer is NOT an easy job. You are smart and have analytic skills other people lack. I wouldn't be too bumped if I were rejected as a PR Manager, I shiver talking to more than 2 persons at a time! One can't be good at everything! (well, very few can, but that's another story)
Also, as others said, talk to a professional; going to a therapist doesn't mean you're going nuts, it actually helps. My sister had issues where she thought she was sick while she were fine, she tortured herself for over a year until she went to a specialist.
She is a whole other person now.
