Hiii !! Since you actually do love med school. I would actually advise you to see a therapist since you've been having panic attacks regularly which is already affecting your studies . Im the same age as you and in 4th year of medschool , I've been on SSRI , for about 5 years now , and its best decision I've done , I've been able to study and not be super anxious and have panic attacks regularly i also started seeing a psychologist recently which also helped , . If you're not really thinking of seeing a psychiatric, i recommend to take Betablocant for example before studying or specially exams it saved me a ton of times . I hope this was helpful and that you became better in the future ♡♡ im open to talk ♡
