Is exercise. That seems to be the one treatment on these boards that I do not see. I have viewed medications, therapy, talking to a friend and such. Exercise is proven to release endorphins which the brain craves.....every single day. High blood sugars and even low blood sugars can cause mood swings. Yet throw in lack of exercise, a mediocre or poor diet, lack of sunlight and you could easily be depressed. I have met some people who just walk for exercise which is a start but at some points that only burns just enough calories that you have taken in. I have been through it all, in and out of therapists for over 20 years, went through a painful divorce, been on medications, lost loved ones and live in New England which gets less sunlight than most other places in the world. Yet I have realized with the one constant of staying in shape, yoga to reduce stress, Vitamin D and finding new adventures (visit new places, meet new people, see an interesting movie) has allowed me to prevail from at least a deep depression when I have personal struggles. I don't feel I put that much time in either during the week, about 10 hours of combined weights, yoga, walking plus eating healthier with fruits, veggies, low sugar and no caffeine has allowed me to feel good. Always love hearing other peoples thoughts, concerns, delights and struggles. Hope you are having a pleasant Sunday.
