How to beat this kind of self deception?

[chath]

I recently realized that when someone hears false judgments about him regularly (like "you are selfish, you don't respect others"), it make them to believe in those things.  Also people use little faults and make them bigger. I think this is relevant me. Now I'm using affirmations and journaling to overcome this and it is working. But I still have doubts. And I need to learn more about this. But I don't know what are terms or how this situations are referred / called.

My questions:

1. What are other techniques?

2. How this behavior called? (How to google this?)

Very sorry for bad English.
