"...what it feels like to be...whatever you are." That's the problem, it feels exactly like what you think you are, but this is only what you appear to be, and this can change in many ways. What you think you are and what you feel like you are are locked in a loop. You don't know what you are; in fact you do know that you don't know what you are but you don't know who it is that doesn't know what you are, or even if 'you' or 'I' is the right word to be using.
