How do you get over Depression?

Hello there people, Let's go, let's help people who have depression by telling tips and ways to get over it. I think that happiness it's a decision really. Sure there's times that serotonin is not being produced and a person might even not get out from bed, but what we need to remember is that it's a time we learned already that happiness can't come from an outside source and only we can make our selves feel bad by something someone said or done, the person actually it doesn't matter how bad this person is has really no control over us. Depression mostly comes from a situation that one can't get over. So in that case thinking about the past and looking for a good thing that benefited you and others is a way to begin the healing proccess, we only can't accept a trauma or a situation we don't understand why the heck we went through.
