Brynna Bantley, 27, was working as a personal chef in San Diego, but had to return home to Atlanta in July after she couldn’t find consistent work because of pandemic shutdowns. Ms. Bantley said she’s been putting off her eventual move out of the house, in part to save money, but also because she’s anxious about leaving home. She worries about being able to support herself without her parents’ help and her ability to find steady freelance work in the hospitality industry.
