To what extent do we create our own environment?

If I feel unloved, is it possible that I misinterpret certain attitudes according to my injury? What if I experience rejection?

Might this feeling of rejection suggest that I in turn adopt a series of defensive or aggressive attitudes contrary to my desire to enter into a relationship? 

In a similar way, a multitude of negative beliefs, undesired feelings and stress affect the perception of reality.

Beliefs such as " No-one will ever respect me", " I won't pass my exam " are sometimes so well anchored that we no longer notice our auto-limitation.
