Hi there justwalking,

"...all test check out" kind of jumps out at me. There is a long list of common problems that can make major contributions to low energy and/or depression and M.D.s don't often check for all of them unless you really ask. Could he/she have meant "I don't see anything wrong in whatever tests I have done"?

See point1 here for some of the common things that could be wrong
