> The thing about this you're engaging in a clear fallacy. Depressed people tend to draw negative conclusions and reinforce their conclusions, therefore if someone draws a negative conclusion (that you consider unwarranted), they are depressed and making themselves worse.

I claimed that depression often leads to catastrophizing, not that catastrophizing is somehow exclusive to depression.

So the "clear fallacy" here is reading a comment about how A sometimes implies B, then attacking the notion that B implies A, despite there being no logical connection between the two propositions.
