Casper,
I can relate to where you are. I am older than you by quite a bit but at your age I was also already very accomplished but had minimal genuine connections to others and was not that aware of my own inner life. I did think it important to let people know how accomplished I was and thought my accomplishments put them off when, in fact, I think it was my unconscious desire to have people see how great I was (yes, this was insecurity in another guise) that put them off.
I agree with many of the posts here. I highly recommend doing some mind-body-spirit work to round out the external successes and gifts you possess. This will allow you to connect with people more readily and not to hold yourself separate from them with your perceived difference or misguided belief in your superiority/inferiority. We are all the same, essentially. One day we shall all be dust and in a hundred years your accomplishments will count for much less than how much love you shared while you were here.
Best wishes to you.
