Hello Noctuary: I'm sorry you have come to this point. I have some sense of what you are feeling. I've always been a person who felt worn out all the time. No matter how much sleep I get, I'm always still tired. In my case, I attribute it to anxiety. I've pretty-much always run on my nerves & I think it has taken its toll. At this point, I suspect my body simply wouldn't know how to function in any other way. I hope that, in some way, you will be able to yet find a remedy for your exhaustion...
