I look older and tired after surgery. Is buccal fat removal reversible?

I am 24 years old and I got buccal fat removal in July 2020. It was the biggest mistake of my life and I wake up depressed everyday. It's only been a year and my face has changed drastically. I look older and tired and my face looks really hollowed. I don't know why the doctor said I was a good candidate, he said I would get the results I wanted. Is there anyway that I can bring back the youthfulness of my face or add fat? I don't want to do fillers forever.
