[My best tip for overcoming depression is] to regard it as being like the weather. It's not your responsibility that it's raining, but it is real when it rains, and the fact that it's raining does not mean that the rain is never going to stop. The only thing to do is to believe that, one day, it won't be raining and accept it so you can find a mental umbrella to shield yourself from the worst. The sun will eventually come up.
