That doesn't excuse her for blackfishing or throwing leigh-anne under the bus with Nicki of all people, laughing while Nicki shreds Leigh-Anne publicly. If she doesn't want public attention or criticism anymore, hence the cause of her triggers, she can just not be publicly available but here she is on the spotlight again, with her newborns, talking about struggling. Like girl go live your life privately and stop complaning.
No one destroyed her image, she basically destroyed her own and almost destroyed the whole little mix brand because she simply couldn't handle the heat no matter how many people tried to help her. A friend only can do so much if you are not willing to get help or be better. She can't hide behind the "but i have an eating disorder" excuse for all the wrong things she has done. Again if that's the case, go get the help you need, step away from the public light and live a private life onwards. Not that complicated if you are not chasing clouds to have media attention all over again. Which that seems to be the case cause she just doesn't know how to shut up and move on.
