My T and pdoc were completely aware of my feelings about the hospital, considered them very normal, and never gave me any reason to feel like I was "crying wolf" at any point. It can be really helpful to discuss this with your therapist so she can help you sort through what is a true crisis and what is a need for a feeling of safety. It is okay to just want to feel safe, and talking about it will actually help you feel that safety whereas keeping it to yourself will increase your anxiety.
