Joel,
You posted a couple of times, then disappeared.
Anyway, I just read your posts on the other thread. Let's be frank: you (a) cannot get into a reputable Caribbean medical school without the completed prerequisites (Biology, Chem, O-chem, Physics, and the labs) and taking the MCATs, (b) will have to tack two years (at least) onto whatever your current plans are, and (c) if you don't go to a reputable school your chances of long-term success rapidly approach the nullset. You didn't say how old you were either. My guess is you're probably in your early to mid 30's, based on what you said in your other thread.
So, if you really want to be a psychiatrist, you're realistically looking at
10 years from now (minimum) until you'll be able to practice independently (2 years of pre-reqs plus MCAT, 4 years of medical school, 4 years of residency). If you go through the trouble of doing the pre-reqs, might as well just apply to U.S. schools. But, as one poster said on the other thread about being an ED physician, you might find it's not what you expected in the end. Also, you're looking at being at least $200k in debt (possibly/probably more) by the time you finish. The current tuition alone at Caribbean schools is over $200K for the reputable ones, for example.
Basically, there are no shortcuts to becoming a doctor. You can't just to do a few online courses then get a diploma from some diploma mill and start practicing (so don't believe anyone if they tell you that you can). I sincerely hope that you didn't think choosing a "cheap" Caribbean school was going to get you where you wanted to be. It is rigorous. It requires passing the licensing exams. And you have to complete a residency and board-certification process in your field. And many schools that
aren't reputable are barred from licensure in many (and in some cases
all) states.
In the end, becoming a physician may take too long and not be the field for you. If you truly enjoy mental healthcare, there are other opportunities to make a difference, and a good living, aside from being a physician.
