I had an issue when I took my MCAT too... funny, you can only plan so much of life, there is always room for unexpected tragedy.
The reason I asked is I've enjoyed your posts on other threads for a while and was kind of surprised when you mentioned you were having trouble. I had read your MD apps, really it seems like that stupid test is the only thing you don't have going for you. You really seem to be the ideal medical school candidate from what I have seen, and you also seem to have a good head on your shoulders.
If you get in just MD, many schools will allow you to opt in to the MD/PhD program after a year or two. Of course, there will be some interviews and such, but by then you will have research experience (if you choose to), it's usually a formality (your research director makes a phone call if you are a good candidate).
Anyway, I am rooting for you.
