I have to agree with Direction - being there for your little girl means taking care of your health and doing what you need to do to get better. Showing that you have enough insight left to realize when you need more intensive care is a huge sign of being a FIT parent.

I'm not sure how they are in Australia (assuming QLD=Queensland?), but here in the US psych hospitals aren't all that bad for the most part. As frightening as the unknown can be, it can be a safe place for you to heal. It can also give your husband a safe place to share his concerns about your illness and help the two of you become stronger as a family. He will probably find it LESS stressful knowing that you are safe in the hospital. I have been hospitalized eight times and have only had one bad experience with a hospital. The vast majority of my hospitalizations have been very helpful and going was definitely the right thing to do.

I hope you are able to find health and peace soon.
