Personally i don't think so. I've had fatigue before I was ever diagnosed with depression but I don't have any answers yet. I had gotten to a place where depression was under control and now trying to figure out the fatigue but the docs hear depression and blame that. They've run tests but everything comes up "normal". It's still a concern I think you should bring it up to your gp and if they're a good doc hopefully they'll run some tests to make sure everything checks out. Good luck!
