I'm 32 years old and have been feeling this way as long as I can remember. To be quite honest, it had to have been in my early teens when I last got a consistent, restful sleep.
Now I've heard that for many Lightworkers, sleep does not equal rest because we tend to be working around the clock in astral form. My question is, what kind of work are we doing? I mean in my situation, it's not a recent thing. This has gone on for a long time.
On a side note, a few times over the years, I would wake up with really negative thoughts on my mind such as "all is bleak, and hopeless". These are not my own thoughts because I don't feel that way at all. The only link I can think of, is that when I was a young child, astral projection came natural for me and during those times, I would often feel and see (not with physical eyes) an evil presence in the room with me. I've been reading that this is the way angels show up when we perceive them out of fear, but it still doesn't explain the negative thoughts unless it's a completely different entity altogether.
