Should nursing still be top of your list for a career then you can explore the different types of nursing out there. As a Registered Nurse you have many options such as working in a hospital, school, clinic, or public health, Even in these fields, you can further focus on whether you want to work with infants, children, adults, and the elderly. Some nursing fields are more stressful than others and you get to learn about some of them while in nursing school. I have to say that what is stressful to one person, might not be stressful to another. My older sister is a Registered Nurse and worked Hospice for many years. I explored it as a possible career path but I found death and dying too stressful for me. My sister, on the other hand, found satisfaction in her job so that it didn't seem too stressful to her.
i wish there was a clear cut answer to your question but there are too many variable to give you a clear cut answer. Much luck in life and in your endeavors.
I am not a counselor or therapist, so, first and foremost, I recommend you discuss this with someone who knows you and will help you to determine what environment will work best for you. Whatever path you take, you will need to be able to manage your healthcare issues. There may be some reasonable accommodations that can be made for you if you declare yourself to be "a person with a disability," but that is best discussed with a vocational counselor. Are you a Vet by any chance? There are lots of programs for Vets. . .
Speaking strictly as an amateur in this matter. . . I think you would do best in a situation where there is a bit of a routine to your daily activity, little or no last minute overtime requirements, and, a bit of autonomy (limited direct supervision). The thing that comes to mind is the radiology field. I don't think you would be a nurse - I think they are radiology technicians. They take Xrays, do CAT scans, MRIs, and other diagnostic imaging. I'm sure there are other possibilities, but that is one that I have noticed on my many trips to doctors and hospitals.
