Should i give up on becoming a nurse?

Im 15 years old and i have nonverbal learning disability. Im perfectly fine at interpreting facial expressions and body language, but i usually need some extra help with hands on things i haven't done before, like sewing. My worst subject is math, they don't even bother putting me in a regular math cl because they know im going to fail it. I do good in all my other subjects. I also have emetophobia, the fear of vomit. Im fine with blood, urine, defecation and other bodily funtions though. As a nurse im sure i would see vomit eventually. I also have a history of catching a lot of colds but im healthier than before. I really want to be a nurse to help people but im just worried im not smart enough, and my phobia doesn't help matters. Should i just give up? I don't want to disappoint my parents by being a failure...
