Hello dear student,
If you are hemophobic which is a serious condition. And in this occupation you have to go through all of this. Practicals are all anatomical based . You have to dissect a human body , you have to do experiment and there are so many things included and everywhere there is blood.  So I would suggest you to not go for such occupation which you can't even tolerate in later life and regret. While you can try for physiotherapy course, or dentistry may be  . I hope this was helpful
Best wishes
