I would also say that testing is really the starting point. It really helps pin-point the damage. I was shocked by the results of my test. I was then able to make the life decisions.

I was living in denial before the test and everyone around me was covering for me at work. I knew I was having issues but passed them off as bad days or not sleeping well.

I would have been fired (and should have been) if I didn't go on long term medical leave. This would have been too hard to accept if I didn't have the hard data.
