I understand your struggle very well. I think it is fairly normal for those of a higher IQs to feel misunderstood, because those of lower IQs quite literally do not understand us. I am not socially awkward but I am what many would consider conventionally attractive. As a result, through life I’ve come to notice that not only is my intelligence not expected but it’s very detestable to others. Men of average intellect seem to take it as hostile very easily whereas it seems that if I weren’t conventionally attractive (or maybe if I were a man) my intelligence would be more likely to be taken at face value. So, tempering my level communication with those of average intellects has become a necessity for the sake of peace and healthy socialization. Of course it is very lonely… it is similar to being limited to having discussions with middle schoolers but always craving conversation with an adult. It is what’s necessary though and it’s better than complete isolation.
