Помогите написать сочинение за и против работы врача.

I want to be a doctor because I want to help people, to treat them, to help to find its feet. I also want to be a doctor because I want to treat my family and all around me were healthy people. But I also do not want to be a doctor because I'm afraid someone is not helping, but rather harm, make things worse. Even more so, I'm afraid of blood.
