Oh yes indeed Zee when we have past memories of traumatic events I only can sleep two hours at a time. It really freaking sucks, wake up in panic mode, and there is so many emotions that it's hard to know what to do. I do take medication for sleep but sometimes it just doesn't work. You just have to work through it. Try to be demanding and don't let them completely take over. I know it's difficult, but you have to sleep eventually, stay positive Zee.
