My goodness, listen man you don't know me and I don't know you. But except for Witzelsucht and a couple of others, I saw the ****-ton of bad advice here. I am both a current PA and a current medical student. I have taught core basic medical science. I don't know if anyone else here is actually a medical student, PA student, PA, or instructor but I am or have been all 4. Perhaps that puts me in a better position to advise you, or not, you be the judge. So my advice: Your ONLY chance to accomplish your goal is to STAY at Ross and repeat the semester. But please, only do that if you FIXED whatever went wrong at Ross. Otherwise reconsider doing something else with your life.
I think you already know that you won't be doing anything in the US Med school wise. You will not get into DO school. You will not get into American MD school. A failure at another medical school, Caribbean or otherwise is an absolute deal-breaker. I just wont happen. Sure, 10 years from now, you might have a chance if you went on to do other interesting medical things, re-took a bunch of classes, grew as a person and rocked the MCAT, But for now, in the short-term, no way. But, I think you already know that deep down inside.
You might be able to get into a lower tier Caribbean school. But you've been down this road already, right?
What you may not already realize is that you will NOT get into PA school either. Some people gave you bad advice here, so let me repeat: you will NOT get into PA school. The minute they see you failed at Ross, you will be round filed. The academics at PA school are INTENSE, they will see your first semester failure as evidence that you will not succeed at their curriculum either. Perhaps if you had left Ross with good grades and gave a story about being home sick and you had the academic qualifications of a PA applicant, you could get in. But if that were the case, we wouldn't be having this conversation, would we? So please, save yourself the heartache. Fix whatever went wrong and do not drop out of Ross, you will not have the opportunity to do anything else in mainstream medicine in the near future if you do.
As far as RN and NP are concerned, I don't really know, as I am neither. Nursing is an entirely different profession and I don't really know how they would react to the Ross situation. Some say the NP curriculum and clinical rotations are less intense than PA school, and may be easier, others disagree. NP is considered a form of advanced nursing anyway so perhaps a failure in med school may not sink you. I don't know for sure, maybe you could call around and inquire.
As far as becoming a Paramedic, you have a chance. The most important determinant of becoming a Paramedic is being a good EMT who is genuinely interested in doing more in EMS. You have to demonstrate aptitude for pre-hospital care and do a generally good job. Everybody in EMS knows everybody else and your reputation will always precede you. But that's about it for Paramedic.
Good Luck and definitely do Pray, it will help.
