So what is positive and negative self-talk?

Positive self-talk is the stuff that makes you feel good about yourself and the things that are going on in your life. It is like having an optimistic voice in your head that always looks on the bright side. 

Example – “These clothes look pretty awesome on me”, “I can totally make it through this exam”, “I don’t feel great right now but things could be worse!”

Negative self-talk is the stuff that makes you feel pretty crappy about yourself and things that are going on. It can put a downer on anything, whether it is good or bad. 

Example- “I look stupid in these clothes”, “everyone thinks I’m an idiot”, “everything is crap and nothing is going to get better”

Negative self-talk is particularly bad as it brings you down all the time. It can impact on recovery from mental health difficulties and tends to make people pretty miserable. But being positive all the time isn’t achievable either, and isn’t helpful all the time. So how can you make your self-talk work for you?
