If you want to stay in the medical area and are open to further training then you should understand that doctors are not the only ones that help people. Physical therapists, radiology techs, nurses, speech pathologists, physician assistants, to name but just a few. Spend a few hours browsing on http://explorehealthcareers.org If you have not already, you should begin volunteering at a local hospital. This will let you see first-hand what many of these people do. Experience is an unwritten requirement for admission to med school, and for schools in some of these other areas they actually require specific number of hours.
As for jobs with just a Bio-related degree (whether in medicine or other areas) I imagine the posters who have told you there are good jobs out there can supply further info.
