Are there any more careers you have an interest in or have thought about at least?
It's perfectly normal to perhaps feel it may not be for you, or even to chose another path. You seem to have a logical head on your shoulders and are more than capable of doing whatever you put your mind and heart to. You have great grades so you could do whatever you liked for the most part!
Experience and things like shadowing have been impossible to get during the pandemic because I have tried it myself. I say just seek out careers advice and talk to other student doctors to gain more insight.
