That the eye cannot see itself does not mean that there is no eye. That was Hume’s mistake. It is the eye that sees. It is the self that experiences. Almost equally foolish is the suggestion that because we cannot point to a single specific entity, we can conclude there is no self. That is your mistake, also made by many Buddhist philosophers. We cannot point to a single specific collection of water droplets, but it is foolish to then conclude there is no river. We are constantly flowing and changing. Our self, our beingness, is beneath all of the labels and attachments we find arise in daily life. “I am an illusion” is self-contradictory. Pop-psychology nonsense.
