Kimmerz that is exactly my pattern too of falling asleep then waking up, and my sister has the same problem. Some of it can be biological, of course, esp. for women in their late 30's early 40s, but for anyone with emotional difficulties it is worse. My sister's MIL is going to die any day now of cancer...hence, her sleeplessness is worse than ever.
So I hope your sitch turns around and if you follow any of this stuff let me know how it works for you.
