The question you poses is whether you should try medications or not. This all depends on your condition. There are a lot of medical conditions that have depression as a comorbid condition. And these must be treated in the first place. Thus a good medical check-up is a good idea. Most of the medical conditions contributing to depression are closely related to digestion, because they may interfere with the proper absorption of nutrients that the body uses to manufacture the right neurotransmitters, such as coeliac disease, ulcerative colitis, irritable bowel syndrome, crohn�s disease, allergies and food sensitivities, candidiasis (thrush), lactose intolerance, grain intolerances allergies to dairy products and so on and on.
As a nutritional psychologist I am not in favour of pharmaceutical medications as a first step in therapy.
Most depressed people have been found to be hypoglycemic, which means they have problems getting biological energy to the brain. The non-drug treatment is going on a hypoglycemic diet, that is a high protein, low refined carbohydrate (sugar-free) frequent snacks diet, plus some vitamins and minerals. This is of course a vast topic and most of the information in this branch of medicine you will not hear from mainstream medicine and psychology.
If you want to find out the connection between nutrition and depression, you need to read a lot outside the mainstream medicine area.
Drug therapy is sold as a panacea for depression, but it is obvious that human biochemistry is too complex to handle by single chemical agents.
