Will jaw reduction help me to get rid of my long face? (Photo)

I am 20 years old. I lost 20lbs weight like in 2.5 months i went on starving.. I feel ugly and unconfident. My face has lost a lot of weight it looks sagging and my face started to look longer .i have sleepy eyes as well . Please help me . Getting a jawline surgery and browlift might help in looking more femine.
