Depression, Anxiety - please help Dr Sameer/Other doctors

I am 38 years old male suffering from depression, anxiety from past many years off-and on. I am an anxious personality, as when I was doing my Bachelors degree, I used to be very anxious during exam time. I did not used to get sleep in afternoon though I would be very tired. Used to have palpitations, anxiety symptoms etc. In year 1995 - I had to face a severe worker strike. Actually I had snubbed one worker in the factory about spitting in the shop-floor. It turned out that all the workers shaved their heads as a mark of protest. I was actually not at fault, since I was doing my job sincerely. Anyway, I went into deep depression, anxiety. Was put on anti-depressant and I changed job. I stopped taking medication after 6 months or so, when I started feeling okay. But after 1-2 years, symptoms re-appeared. At that time, I changed my job again. I started taking homeopathic medication (I think it was remedy no. 69 in Vibropathy) instead of allopathic medicines. I was fine for 2-3 years. But then again on its own, symptoms of Depression, anxiety, palpitations reappeared. I this time took allopathic medicine - Chlomopromine 25 mg. Later on increased to 50 mg. Was okay for 3-4 years or so. But in between stopped taking medication. Symptoms reappeared again. Doctor prescribed Cymbalta, Geodon 80 mg. It helped for 3 months, but then again same problem. Doctor gave Lamictal, Cymbalta, Levox, Zyprxa. Am currently taking it. But no benefit. I really need a natural cure instead of relying on allopathic medicine. PLEASE HELP. Some other symptoms - jumping thoughts, not able to focus, anxious, not able to focus resulting in office asking same question repeatedly. No interest in life. Really difficult to go to office. Need urgent help. Just to inform I have a sweet tooth with regard to taste!
