Perhaps this is a side note to your point, but if when you say "ect" you mean electroconvulsive therapy, then I'll note that ECT has excellent efficacy for major depressive disorder among others and is well-studied: http://en.wikipedia.org/wiki/Electroconvulsive_therapy#Effic...
It is hard to believe that anyone would want an electroconvulsive therapy based on an Internet advice. Even if, no doctor in his right mind will perform it just because the patient demands it.
