re: #464 Nimed
Let’s drop the whole “treatment” thing. Nobody suggested that in the first place, and it’s obvious we don’t require treatment for many mental conditions (for instance, phobias who don’t interfere too much with one’s life).
A phobia is also not a mental illness, though. A perfectly functioning brain can have one or more.
If you want to be less afraid of spiders, or stop believing that the Lord God created the heavens and the earth in six days, a good therapist will work on it with you.
I think being afraid of spiders is more likely to negatively affect your quality of life, though.
