Well, whoever told you that you can't claim depression unless you see a doctor is off
his rocker, in my view. Of course you can have depression and not see a doctor.
The point is you probably can't relieve it yourself until you get on medication to restore the chemical imbalance in the brain that constitutes part of depression. The
rest of it is in your diet and your attitude toward all things around you.
You can change the attitude with therapy or with self-help books, or with cognitive behavioral therapy. You can change your diet most easily of all the self-help routes, and you might wish to investigate some of that. Try reading
Wheat Belly by Dr. David Williams. It will astonish you.
Please go to a website called
http://www.Doctoryourself.com Look down the index
on the left-hand side until you see an article called "Caffeine Allergy" by Ruth Whalen.
If those two sources don't scare the daylights out of you about our diets and what
they're doing to us physically and psychologically, nothing will. We all need to pay attention to that aspect of depression.
Please do go in to talk to a psychiatrist and find out if you do have the imbalance that is fueling your depression.
I wish you lots of success in solving your difficulty.
