is there hope for me or should I do post bacc or try the caribbeans??

This is really embarrassing for me to say long story short due to my bad study habits and lack of motivation/ discipline my gpa suffered in college. I used to be a 4.0 AP student in highscool but now have around a 2.8 sci gpa and had to repeat a bunch of science classes (pitiful I know). I'm starting my senior year so even if I ace all my classes for the fall & winter semester my gpa won't increase much. But my mcat score is a 519 and I am working on getting my EC's, shadowing, and... is there hope for me or should I do post bacc or try the caribbeans??
