Contouring methods for protruding cheekbones and sunken cheeks

As I get older, I notice a lot of changes in my face as well.

At some point, I started thinking that my usual makeup routine wouldn't work anymore.

My cheekbones stick out and my cheeks are sunken in, so when I take pictures, it's really...

Now I don't want to take pictures anymore.

What should I do in this situation?

I've never done contouring before.

Now that I'm actually about to do it, I feel overwhelmed and scared.
