When the reality of something upsetting starts to sink in, your mind just seems to be thrown into a blender with its lid taken off. Bits and pieces of thoughts and emotions gets ripped apart and go flying off in different tangents. You just can't seem to put it all together as everything is just so fragmented and out of control from your prespective. After some time, when you do manage to pull yourself through it all, although on the outside it may seem that you're alright, the scar inflicted on the inside from the experience will most likely stay with you. Is that why people sometimes say that they can forgive but will never forget?

It doesn't stop there yet. The whole thing will then result changes in perception on certain things which will then become the basis for a defense mechanism that gets built to avoid falling into that upsetting situation in the first place. Is that why people sometimes change so drastically after having encountered those situations?
