I have somewhat similar experience. I shifted from a small town to a metro city for pursuing my undergraduate programme. I was alienated from the whole class for not being 'cool' or 'hip' enough to hangout with them. External biases made it really hard for me to make friends.

It took me time to get comfortable with who I am and what are my values. But still, I have an inferiority complex which hinders me to get along with anybody as the college experience still loops in my mind saying I am not enough.

When Breath Becomes Air by Paul Kalanithi, it's a memoir of a neurologist who comes across lung cancer himself and how his life changes from being a doctor to the patient. I recently finished reading it and let me tell you, I had to pause every other page to reflect upon those words as they were surreal.
