["One of my coworkers got the promotion I'd been vying for. I'm trying to be happy for her.", 'That must be hard having to be happy for someone that has what you wanted.', "Yeah. I'm trying not to be jealous, but it isn't working. I really wanted that job."]
It's normal to be jealous. It is a product of goals not fulfilled.
A coworker got a promotion at work that I really wanted. I'm trying really hard not to let my envy show.
