She's never been grounded in reality, so there's no way she could adjust back.
Even with her sad little ''muh trauma/foster care'' bullshit, she has been coddled and sheltered from an early age until today. Coddled by foster parents, coddled by ''friends'', coddled by girlfriends, coddled by girlfriends parents and it was pretty evident even the people she worked with at that care home (for a very short period of time) allowed her to act her cunty self without putting their foot down.
I don't think she has a single solid connection to reality. There is no humble origin to return to, just more mooching.
Everyone in her circle has always babied her. They've fed her, clothed her, given her a home, ferried her wherever she wanted to go, found her jobs and tried to aid her weightloss in realistic ways that bloody worked until she threw tantrums over it.
She can't leave YT but if she has no choice, she'll rot and die unless Becky decides to work full time to support her fat twat fiance. Amber and reality don't mix.
