Pursuing a career in healthcare? Where should I go from here?

Hi all, I went to a caribbean med school a while back, but things were getting expensive during my time doing clinicals so I had to put it on hold. I don't necessarily want to finish med school, i feel as if I would have to start back over from the beginning and my heart is no longer 100% into it. I do love science and health care, so I would like to stay involved. I am currently working as a support provider for autistic children while I also do per diem work with sports teams/companies as sort of a passion project. I wouldn't mind going back to school and working towards something that pays better but also has a pretty flexible schedule so that I can continue to pursue sports on the side. Any suggestions would be greatly appreciated. Thanks
