I have skin depression around my mouth and sagging cheeks. What should I do? (photos)

I am 33. I don’t what would help. Adding pictures. I am open to all recommendations to make me look happier. I look sad. I have some nasolabial depression. Very weird looking. I look like a sad bad person. I laugh a lot but I don’t know why this is happening to me and what would fix it. I also here a lot about my chin is being too sharp, my cheeks being too flat and my nose being too sharp. What do you think? What should I fix first?
