How gratitude brings peace to your life?

live for other people not yourself and don't think about your worldly desires and don't want or look forward to peace and happiness and just experience it that's all you need in 99% cases and if you think your depressed your probably not your just think about yourself,don't tell a doctor or a therapist that can prescribe about feeling sad no matter what he says, he will tell you your depressed and need an antidepressant when your not really depressed on purpose because they can get paid from a pharmaceutical company if they sell a certain amount of their antidepressants (that increase the chance of suicide for people taking it) that are really really bad for the chemical balance in your brain that's why people get little emotionally numb or turn zombie like almost its not that obvious all the time but they are very very sick selfish people that make antidepressants they give them to dogs that need exercise, kids, almost all foster kids and starting to give them to infants that have "signs of depression its all for money
