*tackles*

I sometimes have a hard time figuring this out too. How I usually tell is if it feels more physical or mental, like if it's just from karate/exercise yeah I'll be physically tired but still functioning fine. If it's from depression, I'll be tired in the sense that my butt feels glued to the couch lol, just like a weighed down kind of tired. I also feel tired mentally, like I can't think very clearly, and I'm much more likely to nap.

Another way to maybe tell the difference....when you think about or plan to work out again and if you consider not going, is it because you're physically sore and/or tired, or just don't feel like going even though you feel fine physically?

I hope that made sense....
