Im sorry your still struggling and shes not as helpful as you would like, But maybe there isn't much more she can do with CBT.. When I have really been struggling Bipolar wise the only thing that has helped is med change..

I think you should head to bed in a couple hours and just stay there... Hopefully you will be able to fall asleep earlier, staying up late each night isnt going to do you any good. Do you enjoy reading ? I know that is calming for me, I escape my life and fall into the story.. Great Distraction..

I hope you sleep tonight
