I think Emma's biggest wish of instant gratification was with her WLS.I’m not surprised Emma is feeling depressed, she is a failure in most aspects of her life, she has no purpose and no drive. However instead of helping herself she expects someone or something to sort it for her.
Emma is all about instant gratification and would rather take medication (or in this case increase it) instead of improving herself. Exercise, eating better, routine, work, socialising, volunteering, haircut, wash, therapy etc will help her feel miles better.
She is so quick to give up, any sign of negativity and it’s a nope day. She gave up on her therapy because she was cured and didn’t want to address deeper issues which I think is the route of all this.
Yes you can have surgery to remove half of your stomach but you cannot still eat as you wish and loose weight. Just highlights the lack of effort Emma wishes to put into any of her goals or struggles.
