I read this by chance and I don't know how to express my apologies for the concern. But I know who you are referring to and as much as it pains me to say it, I can only tell you that the person you are looking for has returned, with a different profile, a different story and that she has searched for each person she has left behind, to try to redeem herself.
This person left for personal reasons, for something she couldn't control in her real life and immaturely thought of leaving everything. She was and is going through a serious situation that she prefers not to make public and she is very sorry for everything that happened here. For leaving without saying anything. For not asking for help. She says that her comic (Broken) will not come back, but she promises that what she is doing and what she wants to publish in the future will be her motivation to continue and her way of apologizing for worrying so many people.
She vows never to disappear or disappoint the people she met here again. That's really all I can say about Amenity.
