Yes people have felt this way, and many people who felt this way are doctors now. Yes you can do it. Whether or not you want to do it is going to depend on how badly you want medicine vs. what you need to sacrifice to get in. I´m not sure how much we can help you in terms of making that decision, it seems like something that you´re going to need to work out through introspection, discussions with family, and (especially in your case) prayer. Where we can help is helping you figure out how to minimize the pain of getting in and also figure out how far you have to go. You might be surprised how many options this forum can present you with if you´re more specific about your situation. If you want help with that post your GPAs, MCATs (practice or previous) if you have them, and what your obligatoins are (family, job, whatever). Right now your situation is sorta general to give you more than equally general encouragement.
Edit: I looked over your previous posts. You currently have a 2.6 with no prereqs. No details on your financial obligations or debt other than that you ´have debt´(does bible school really charge that much?). That means you have the opportunity to get to a little under a 3.0 with the prereqs and a much higher science GPA in about a year if you devote yourself to college full time (longer if you can´t, but the GPA thing still stands). Assuming you do well on the MCAT (32 or more) you then have the three options of either
1) Take another year of undregrad after the prereqs and trying for DO
2) Trying for an SMP, doing really well, and going allopathic
3) Going to the Carribean and trying to graduate (less than half do)
Best case scenario you´re in a US allopathic medical school two years from this fall. Not easy, but definitely not impossible.
