Jealous of a friend

I recently saw pictures of an acquaintance on Facebook and it brought up old feelings of me being jealous of her. She is super cute, athletic, and fit, all things I would like to be. I’m not sure how to navigate this feeling of jealously.

Here is my model

C: I see picture of her
T: I wish I were like her
F: Jealous
A: Judge self, ruminate, don’t do anything to develop myself
R: I stay stuck, reinforcing thought that I wish I had the qualities she had

I’d appreciate any help with this, thanks.
