I don't understand why people can stay depressed for such a long period of time. For me, if I fought and found it not worthwhile, I don't see a point in trying any further. I don't want to waste my time on things or people who don't deserve it. Or you can call this... I don't know whatever you want.
Giving up is easy, as well as moving on. The decision to make changes to your mindset is the toughest. And the key to solution.
