So, and I agree, the science has not progressed enough to be able to tell, but if the possibility exists that it is of biological in origin, do the docs withhold medications that can help? To me that is inhumane treatment.

As to your example, there are some mental health issues that are purely psychological, and others that are based in biology. So, yes you would get people that wouldn't test positive for a chemical imbalance, but still show the signs of depression, but medicine can still help them get over the hump.

Personally, I went more than 6 years taking a mood stabilizer and ad w/o a problem, and no other intervention. I was just fine, until I decided to stop taking them, and started the swings again. I've been fight this for 30 of my 40 years, and I would be a fool not use every thing I can get my hands on to fight it.

I'll ask you the same question, is it right to withhold it if we don't have proof?
