I'm glad she seems to be doing a bit better.
I'm a bit conflicted about hospitals. I've been to better ones, and I have been to awful ones. I would suggest supporting her, but also listening to her concerns. A place can sound amazing online, but be totally different when experienced. It can certainly always be scary, and often humiliating, but if she talks about not being heard, or about staff being unprofessional, that may be accurate... the doctor should spend more than 30 seconds with her in the hallway, they need to keep confidentiality, they need to be respective and keep her feeling safe.
The best hospital experience I had was frustrating and humiliating, but also safe and supportive. The worst one treated me like an obstacle in the way to getting through their days.
Keep listening and encouraging her. (Hugs)
