I worked as a biotech recruiter for a startup during its entire six-month lifespan several years ago, and job-hopping is an automatic resume red flag for many companies, and like Tucson said, you are indeed job-hopping. A company wants to know that if they put the money and effort involved in recruiting and hiring you, you will prove a good return on their investment.

Your BP diagnosis is potentially prejudicial private health information. Beware the stigma. If I was interviewing a prospective hire with even a couple job-hops on their resume and a bipolar diagnosis pinned to their lapel, I would bet hard that they would soon be hopping out of the job for which they were interviewing. As brilliant and as perfectly-suited for the job they might have seemed, I would hear in my head Rutger Hauer from Blade Runner: "The candle that burns twice as bright lasts half as long."
