By "relapse" do you mean a bipolar episode, or do you mean you're having a big time flare up of your anxiety disorders and you're having panic attacks?

When you have insomnia, those late nights/early mornings can be the witching hours for anxiety. For some people, it's because they feel more alone. Other people here are awake for the same reasons, and knowing that may help you feel a little less alone.

I'm so sorry you have to deal with this degree of anxiety so often BF. I wish your life was more peaceful for you
