A few years back I got hit with depression my child got on drugs, I was trying everything to save her, but as we all know you can't do a dam thing until their ready.I had gone to the doctor with dam near nervous breakdown. I tried the zoloft I just didn't like how I felt. To add I didn't want the pills, more so because my child was on pills. So I decided to go to a all natural oriental doctor. He helped with the depression issues without the drugs.
Their are some scents that will help a lot, essential oils, candles. Scent of lavender is good, peeling a orange the smell of citrus helps.
See if you have a holistic doctor in the area, that might be something to consider.
