It takes a 10 min talk with a doctor to get antidepressants around here. Perhaps a test which looks like multiple choice score of symptoms with some weights.

I had an old gf receive two different drugs each with terrible side effects. To me it looked as poison.

I decided that I would rather hurt myself myself than fuck with my brain chemistry this way.

During the dark northern Winters I lack vitamin D (your doctor can measure this using a blood test). The symptoms are some physical issues and probably something that can be described as light depression which goes away if I remember to take the vitamins.

We are all different. Some people might need anti-depressants. I just need some vitamins.
