I honestly think she freaked out when the clinic was going to give away/destroy her embryo's as she couldn't afford the cost to keep them in storage anymore so her and her doctor made a very poor judgement call to implant them all. She knew the risks, but chose not to care. It's sad really.
I can't even imagine how crazy her situation is as I have a 9 YO and 4 YO and I can barely get any rest.
