I agree with Tweety about the health problems. All the nursing programs I am aware of require a physical before you start clinicals. Many health problems, especially if they are currently being managed, would still allow you to become a nurse, but there are some that would make it highly unlikely for you to be accepted into a program.
Schools do not want to give a slot to someone who will be unable to manage the physical components of training, let alone the job world. They don't want the liability of taking on a student who could be further incapacitated by the demands of nursing school. And the reputable institutions don't want to give you the false hope of being employable when that is unrealistic.
Nurses who acquire health problems after they are licensed can usually find a less physically taxing position, but that is because they have experience that can be put to use in a different setting.
I would contact some schools in your area and make some hypothetical inquiries about your specific condition to see what kind of response you get. Depending on the type of condition you have, they might have specific requirements a prospective student would have to meet to demonstrate that their problems are manageable and under control.
It's better for you to find out what you're up against before you invest too much financially, physically, or emotionally.
I wish you success.
