I wanted to add my experience to the dietary reccommendations. My depression has vanished since I added more fat to my diet and since I have been taking a b complex pill everyday. I now eat a tablespoon of cocunut oil in my tea each morning.
Many people who have adopted a low carb diet with adequat fat and protein have been able to get rid of there depression. Protein is great but please don't forget the fat!! And no fat does not make you fat! In my opinion carbs do!
Hope this helps someone!
When I was younger I was sad most of the time and often had bouts with fear. Mine turned out to be dietary. I ate a standard US diet with plenty of sweets and refined foods. I also drank a few times a week and the drinking would deplete my body even more than just the crummy diet.
On the insistence of a friend, I started taking a high dose multiple vitamin from a health food store, plus a separate vitamin B supplement, separate vitamin C supplement, and separate calcium, magnesium, zinc supplement. I also cold turkey cut out all refined sugar, soft drinks, coffee, and refined flour. I ate about three pieces of fresh fruit a day and had three servings of fresh vegetables per day. I got my protein from meat and cheese, and ate whole grains like whole wheat bread and brown rice. I also exercised 20 minutes a day, five days a week which I had to force myself to do at first.
It worked for me and 35 years later I still follow this regimen, although not quite as strictly as before. I continue to be optimistic and I think I have a normal energy level for someone 65. Once I started to feel better, I experimented with dose levels, but I take well above the recommended daily allowances every day.
My own view is that medications just cover up the symptoms and may actually contribute to the problem. I hope you are able to change your life to one that you enjoy living; time keeps running out.
It worked and I continue today to be optimistic and have normal energy for a 65 year old.
