Shall i stay on or go?

I have almost done my AS, I have six weeks left. I am debating on staying the final year or to go to college. The reasons why I would like to go to college is because every day I dread in sixth form, I really do not enjoy it or any of my subjects apart from Health and Social care. My grades are not good because I do not enjoy the subjects, so I feel if I do go to college and study Health and Social I will enjoy it and get really good grades.

In the future I would like to work with disability children, would I need A-levels to do that? And what course do you think I should do in college to be able to do that , I am not sure what to do, I am so confused.
