As mentioned before, very few options that involve using your MD. You can't get a license without at least one year postgraduate training, and some states require two or even three. An MD is only an academic degree, like a Ph.D. but not as widely accepted, without a license to practice. You won't be able to get an academic post without a postgrad spot, as a previous poster mentioned.
You could teach at a community college, do 'consulting', or do something else entirely.
You have to make a decision at this point. Do you want to ever practice clinical medicine again in your lifetime? If not, then doing a residency is probably not a good idea. Remember, however, that you're probably feeling pretty bad about medicine at this time but any time in your life is better than internship.
However, if you think that you might want to practice medicine at some point in your life, you should consider at least finishing an internship. There are some pretty cushy residencies for those who don't want to work too hard, especially in Family Medicine, PM&R and Psychiatry. Some FM residencies have almost zero call, 9-5 work hours and weekends off, and they're pretty easy to get.
