(I am the OP on going through loss and sadness and not being depressed.)

Yes 100% correct. Just like if you have heart disease or a bad back their are non-medical activities that will help those medical condition. My statement is that their is a medical piece that people discount and/or actually dismiss. A person can't just "fix themselves" and having the medical piece help them with treatment with counseling is a big help. Depression isn't that your sad.
