Can't see there is much else you can do if she is in a state apart from what your doing which is not getting sucked in, but resisting getting sucked in is tiring. I found reading this everyday helps: http://www.kipling.org.uk/poems_if.htm
My W recently went for professional help and got diagnosed despressed, I not sure what finally made her get help. I think it's important though that they see it as a positive step. I think admitting you need help can make you feel like you've failed and so people fight it. So anyway you can paint your own experience with your Psyc in a postive way, so she doesn't see Psyc as someone against her or as someone to go to because she's failed, may help.
