Pre bipolar a long time ago I suffered from severe post natal depression. I was put on Zoloft and attended fortnightly therapy. I think it was the combo of meds and therapy that helped me overcome the depression.

My son started suffering from ‘low moods’ at 18yrs of age. I was told with children and teens that exercise etc was equally as effective as meds. My son started exercising outdoors an hour a day, taking Vit D and meeting with his youth pastor weekly.
I would say he’s doing pretty well now.
