Ask photographer to hold a mirror so you can have some comparison.
Joke aside, your eyes have compression effect that is similar to 50mm lens which is rarely used by phone photographers. That will make some distortions in perception.
Also, your eyes are not on the center of the face but rather on higher side. That by itself add some distortion and makes features around eyes look bigger = bigger forehead, smaller chin.
Salt to injury, phone photographers never raise their phone to eye level, which means it will exaggerate the features that is closest = bigger chin, smaller forehead.
This is assuming that your photographer use phone... If the photographer use 50mm and use same lighting as your bathroom and always use viewfinder, the result should look rather similar to what you see in the mirror.
