Depression is a different problem from performance anxiety.

[dredmorbius]

I'd appreciate seeing your sources on that.

[WalterBright]

They're distinctly different emotions. You might as well ask me for a cite that being angry and being happy are different emotions.

[dredmorbius]

That's an assertion, not a source.

[WalterBright]

I think you're pulling my leg.

[dredmorbius]

I think you're wrong.

If you don't have a source, you can simply say so.

At this point, I'll simply presume as much and move on.
