How can i confirm who is my GD and not be delusional?

[Oroboros]

I followed the steps provided by HPL, sometimes i hear nothing mostly i hear a name, and yesterday i heard another which made me confused

I am Drawn to 3 names and im pretty sure its one of them since i cant even look at other names, i feel strongly its one of the 3, and 1 of them i feel closer to than the other 2, this 1 is the one i hear his name 99% of the time when asking

Is there a way to get a final confirmation? Or should i wait until i hear voice that isnt mine instead of my own voice in my head? Since i see many after starting are "sure" about their GD, can you please tell how you confirmed? Thank you
