I am in career choice dilemma ? Need help

I am in career choice dilemma ? Need help I know i have done this kind of post before. But i really need honest advice here. I dont totally agree with the mindset " you can do whatever you want to , just set your mind to it and work hard".sometimes its not possible. Well, the career i want to pursue is medicine(MBBS) after finishing high school. But i feel that my stammer wouldnt let my get through it , especially for the kind of stammer i have. (Excessively long blocks). Theres just so much competition in this field of medicine that i feel like having a stammer would just disqualify me. I mean there s not a lot of people struggling with the problem i am in medicine. Talking fluently and being articulate is such a huge part of not just medicine but every other career field. Most non stutterers take this part for granted. I dont want to get into this medicine and feel stuck somewhere in between or after i graduate from medical college cuz that would be me working in that field for the rest of my life. I dont want stammer to influence my career choice but i dont know , i feel like excelling in medicinal career feels impossible for me at the moment. It has really become hard for me to choose a career as me being a person who stutters moderately and sometimes severely. I ve also tried speech therapy without any significant results.
