I've had similar issues. The only thing that seemed to help was kinesiology. Its a way to talk to the innate intelligence of the body. Of course it had to be a specific protocal, which I must admit took a while to discover. Email me if you would like more info. I now practice chinese medicine and kinesiology. I could inquire about a practitioner in your area.
BTW I'm only 26. I went through a lot in college and I worked hard to figure it out.
When you say "no one knows" well in many ways you're right. Learn to communicate with your body. It has a story to tell. It can tell you almost anything and it cannot lie:)
