My iPhone doesn’t recognize me

 What does this mean when I look at my iPhone trying to open it with my face but then it says I’m not able to recognize you why does this happen? Is it my face is being changing is it because I am just waking up or I am not able to wake up at all is it because my hair is not in the normal style when I did the photo for the face recognition it really depresses me that I am not me that the iPhone doesn’t see me as me and then I think maybe it’s not only the iPhone maybe other people also see me not as me. Maybe it is how I reflect. My image is not really me so if you look at the people and if you look how you communicate with them mostly they are just communicating back if you go with a smile, they come back with a smile if you go with Fran, they come back with a front so it’s basically You are your reaction or your expression that is reflecting to the other side so if you reflect a good face. You will get a good face back and if you reflect the bad one, you will definitely get a bad one back just think of it. My facial recognition doesn’t work because I am reflecting the wrong message.
