cookie, i think you've been accepted into a few schools based on the assumption that you would have your bachelor's prior to matriculating into med school, which you indicated on your AMCAS app you would have by june. there are a few schools that will take people without a bachelor's, but it is extremely difficult to be accepted this way--a college degree is strongly preferred. had med schools known that you weren't planning on finishing your degree, there is a very good chance that you would not have been granted an acceptance because you would have been evaluated in a different light. so to have an acceptance in hand and then suddenly decide not to finish college may be seen as 1) falsifying information on your application and/or 2) not fulfilling the final requirements that your eventual matriculation is contingent upon, and you may risk getting your acceptance revoked.
why would you go through 4+ years of college, only to not get the final degree in the end??? if you really want to take some time off, defer med school for a year.
