I tend to agree with the comment suggesting getting trained to become an x-ray tech, or an mri tech, both of which pay fairly well, and allow you to avoid bodily fluid exposure. You might train to be a nurse and get over your revulsion, but again, you might not. In school, you have to learn the basics of patient care, and after graduation, you need to get some patient care experience to move beyond bedside nursing, and that's a lot of blood, BM and sputum in the meantime. You also don't explain why you want to become a nurse, all of which reasons you have to be able to hang onto to get through the parts of nursing school which are difficult. If you can come up with 5 good reasons to endure something you know ahead of time you can't tolerate, and you feel exposure to these things won't make you throw in the towel, go for it. It's hard, but people do it every day. Good luck.
