I struggle with depression as well. I cope as naturally as possible because I dont want to be dependant on medication, but it seems this chemical imbalance is winning the battle. New Zealand is right, start excercising. Your body releases endorphines that will give you somewhat of a natural high, but overall a mood brightener and confidence stabilizer. This is your best bet when considering natural remedies. Hang out with friends when you can, but I know im introverted and insecure and dont always like doing that. Its hard man, just start lifting. Pick up a hobby, reading is an excellent choice.
