Long Oblong Face Be Made Shorter by Lowering the Hairline and Altering the Jaw? (photo)

Your hairline can be lowered for better facial proportion and your jaw is fine. Your face is pretty and you might want to discuss "feeling ugly" with a therapist before having surgery. 

Before you consider surgery, I would urge you to reconsider how you think about yourself. Your face doesn’t look long or oblong and you certainly aren’t ugly! It appears quite proportionate and feminine.

 No.  The way to aesthetically improve a female face, that appears oblong, is to improve the shape of the cheeks which in the photo appear quite flat anteriorly (front).  The hairline being lower will not make the face appear more heart-shaped which is the aesthetically ideal female facial shape.  

 Similarly, making the jaw or jaw line more prominent is a male trait and will make the face appear more angular and masculine...not something aesthetically beneficial for a feminine face.  IMHO, you should find a MD that understands and follows the proper aetshetics of facial beauty for some fillers (I like using Perlane) to augment the cheeks so you can see the feminizing results.  After that you can consider cheek implants if you are age appropriate.
