Easier said than done, you might say. Before my breakdown I was regularly waking at 4am, and failing to go back to sleep.
The more tired I was, the more anxious I became, and the more anxious I was, the worse I slept – and so on, round and round in circles.

One of the happy effects of doing exercise is that it exhausted me. And my guess is that allowing myself to talk honestly relieved me of some of the burden of anxiety that spoiled my sleep.
One thing I’ve noticed: I have a lot more dreams than ever before. When I told my therapist, she said that’s a good sign.
