I am not saying relationships are the ONLY factor. Your friend seems one of the intelligent people who kinda drive themselves crazy. Maybe depression comes with high IQ. I have not met person with high iQ without issues.

But was just opposing the whole "depression destroys your brain and ADs protect it" claim. Especially since this "illness" is very hard to define.

I could come up with claims of past life, hypersensitivity, psychiness... but that's kinda far off in drug forum, heh.
