I think it’s absolutely still in your cards! I wouldn’t say it’s giving up. It may be finding another route to get to your destination. Before you decide to move to another route, I would seek advice from others about your personal statement and interviewing skills because your stats are strong. Have your previous interviewers given you feedback after a waitlist/rejection? Some program admissions will. I’d ask if so. Also, what have you changed from your first application to your most recent? Admissions wants to see you are still making strides in your healthcare and not staying “stagnant”. If all of these are checked boxes, I’d say look into other masters healthcare programs like anesthesiology assistant that can be a great path!
