您退学的权利和要求获取医疗帮助的权利是完全两回事，除非您能够真实的证明出因为学校医疗服务的玩忽职守导致了您的损失，您可能很难从学校的医疗部门获得任何的赔偿或者使他们为您支付任何的费用，这其中包括学费的损失，即使您选择从这个学校退学。
Your right to drop out of school is independent of your right to get medical care, unless the student health service committed malpractice it is unlikely you will be able to expect them to pay for any costs you suffered including the loss of tuition if you do not continue with the school term.
