I Am 25 Years Old and my Skin on Face is Sagging Like an Old Person, What Do I Do? (photo)

Im almost 25 and my face is saggy like an old person. People regularly think Im in my 40's. It is impossible to live a normal life when every person you meet is flabergasted when I tell them "no were the same age" then have to watch their reaction. I feel I am cursed, I have never met anyone else who has skin sag like mine at this age. I am a happy go lucky fun person but due to what I see in the mirror every day I have turned into an anti social intravert.
