I always think it's best to tell the whole truth, even though it's hard sometimes. If she thinks you need to be in the hospital or have some meds, so be it. It's not like she gets a bonus for every person she sends to the psych ward; she has your best interest in mind. Getting better is a long process and, the truth is, sometimes you need to take a few steps backwards in order to do it. It'll be tough, but I think you can do it!
