I agree with the other posters that you should be proud of achieving so much, thus far.

You have to ask yourself, "where are these deep shameful emotions coming from?"

You have a long road in front of you, and I see that you are struggling with something by the meds you are on. So be that as it is I would consider you an over achiever!!
And like everyone said, your GPA is only part of the overall picture that schools look at.

Some of the more "prestigious" med schools hold that honor by name only.
You are in control of your future do not compare yourself with others, this will lead to more anxiety and frustration.

Look into the schools you are interested in, the programs they have, and find the right fit for you.
