How do you deal with depression?

Some people say to me the best way to deal with depression is to see a therapist.
I’ve heard MANY ways to deal with depression, for example : Three of the more common methods used in depression treatment include cognitive behavioral therapy, interpersonal therapy, and psychodynamic therapy. Often, a blended approach is used. Now these examples were from my mom, but look how different they are when they come to my dad : Age. Major depression is most likely to affect people between the ages of 45 and 65. “People in middle age are at the top of the bell curve for depression, but the people at each end of the curve, the very young and very old, may be at higher risk for severe depression,” My dad thinks depression affects people between the age of 45 and 65, but I think not. Who do you think is more correct my mom or dad, I guess my question is how do YOU deal with depresion
