A clean well lighted place

I've always been of the opinion that when you find yourself depressed, or terribly sad, then the best general way to slowly get back to life as you want to live it is by creating something which excites you. It helps if you are a creative person to start with, but if you aren't, troublesome emotional situations probably offer the best excuse to pull yourself out of the rut and apply your mind to coming up with a reason to feel good about yourself.
