Define insanity. He certainly suffers from a deep pain in his soul, he is not fully sane anymore and goes "wayward". That could be either extreme depression so he actively looks for isolation, or he really is so disturbed he loses his senses of orientation or maybe even both.His spirit/mind/heart certainly is not healthy any more, that is why this happens to him.
Then actually he should fade or die of heart break as an elf. The connection between an elvish spirit and body does not allow for one to "lose his senses of orientation". He could be looking for isolation sure, but I do doubt he could stand that for more then a few millenia without fading either. Or he is later joined by Maglor in the "restless singers' band". But insane I cannot see how.
