I can relate, so much, to this. My mind just doesn't want to rest. I have so many thoughts, they keep me up. My mind doesn't "race" like with bipolar, but it's like I have too many thoughts at once and I cannot organize them or filter them well so I end up writing half the night and it comes out incoherent. I often am awake until dawn when things get worse for me. And I hate sleeping during the day. Gah! I've been a chronic insomniac since I was a child, I don't remember ever not being this way.
