All jokes aside :
Think \'Clean Slate\'. Make up the balance of all things in your current life and appreciate what you took for granted too easily.
Starting from scratch on a number of things helps to look at things more objectively.
The fact that i am healthy, still have enough money, have time are examples of aspects alot of ppl don\'t even have in this world.
Furthermore, if you don\'t specify \'depressed\' more than that, this is as specific as advice can get.
