Was there any element of protecting you, making sure that you would be safe from self-harm, in her wish to send you to hospital? It doesn't sound so from your description... if you need to be kept safe, then you should go (in my opinion), but if not, it has to be your own decision. If it seems pointless then it would maybe not be very helpful (but this is coming from somebody who is very biased against psych hospitals, so take my advice only as one personal opinion from somebody who doesn't really know you )
