Insomnia, I think most people here suffer from that. Its ok, there is nothing wrong, I've been an Insomnic for years now. I can go nearly 3days now with NO sleep at all. But I recently I have been able to sleep for longer, and more regualy. But the Nightmare are still there, the voices in the dark, in my head. It'll take time, a long time!
Dont feel bad about not being able to tell befor last week. Your stonger than most, You should feel proud that you where able to.
Your not going crazzy, your just starting to heal, come to teams with everything that has gone off, and find ways to deal.
Stay Stong, your doing great!! And vent as much as you like, its good to get things out, even if it is on paper!!
