Hang in there! Im so sorry to hear that the last two weeks have been so stressful and worrisome
Maybe If you keep her in (open) crate in your bedroom away from visitors and noise, Tv's & stereo's etc.. maybe some soft music just so she will be use to the everyday noise, put a blanket with your scent on it along with a toy along with her food and water and maybe she will come out when she is not feeling so frightened. Maybe there are two many people handling her? She sounds like she is not handling being away from her mamma and to much excitement
good luck and please let us know how she is doing?
