Do you mean you don't think you can handle the bedside part of nursing school, or nursing school in general? If you mean in general, just know that any program for a healthcare profession (especially if you want to work in the hospital) is going to be challenging and competitive.
Have you considered OR nursing? It's completely different than being bedside on a med/surg unit and (at least in my area) the OR will hire new grads if you completed your IP there. There are other nursing positions that don't require being at the bedside, such as informatics, leadership positions, and case management. However, I believe many of these positions require some bedside experience and for that reason are probably not of interest to you.
There are many jobs in healthcare that don't require as much bedside time as nursing, or none at all, but you will need to do your own research to determine which one best meets your goals and interests. Some that come to mind include; physician, PA, x-ray tech, tele tech, HUC, pharmacist, and dietician. When you find a position you think you might be interested in I recommend shadowing someone and researching not only the position, but the schooling you will have to complete in order to obtain that position.
In my area, the PA program is a Masters program so you must have your Bachelors to apply and complete the GRE. You should contact schools in your area or search their websites to find out what their specific requirements are.
