It sounds like storage is her primary concern. If she needs a full bed, she could forego a nightstand and use a tall, 36" wide highboy dresser or a desk with hutch, depending on her needs. A full bed is 4.5' wide, which would leave 3.5' for the dresser unit to the side if she's got an 8' wide wall, and she can make use of the tall storage. I can't give the best advice without seeing a floor plan, but I would consider removing the closet door if it interrupts furniture placement, and hang a curtain instead. Also, something like this bed could work well for her as opposed to lifting the bed like in a dormroom:
