I like the idea of positive psychology. 
Instead of studying what’s wrong with us to eradicate it, study what is right to emulate it!
The stoic philosopher Epictetus believed that: ‘It’s not things that upset us, it’s our view of things.’
We all have inherent tendencies to certain negative thoughts that evoke unhappiness and disturbance. Once we accept that fact, we can learn to spot these negative thoughts as they arise and then challenge and re-think them.
Or just stop thinking negatively: 
Cognitive therapy is all about learning about how our thoughts create our moods; I can recommend it.
It teaches one to test one’s negative thoughts, which become beliefs which become thunderstorms.
Looking at them closely discloses their falseness, so they can be discarded.
Fill that space with good thoughts!
