That sounds like depression, to be honest. As someone who has depression, and is trying to get better, my best advice is to start by at least mentioning it to my GP. Doctors can help!
I think burnout is a kind of depression, but a work-related one. I don't suffer from apathy in my private life, still have some interests and hobbies, but at work i feel i'm going backwards.
BTW thanks, I really hope this is not a depression. And good luck.
That is why its such a difficult situation. when you have depression you may not want help, due to the negative affects of depression controlling your actions. Burn out still allows you to want to get better. The up side of depression is that typically with medication and or therapy you can get better. Burn out really only has two cures: changing jobs which is a pain or your work changing which is usually out of your control.
