It’s lonely at the top, I know. But that’s a common experience for anybody who has unique and interesting ideas that they can’t express properly or find anyone to share with.
In your case it may be an IQ point that puts you in a smaller bracket. In another case it could be someone whose lateral poetry or artistic style has more layers of symbolism than can be expressed in writing or explained and thereby missed by all but a very few individuals.
So in being isolated, you’re interestingly not alone.
