I would like to point out something you said - "I am not the person of their expectations", and this has eventually made you doubt yourself. Wow! So to me this seems to indicate that somewhere within you feel inadequate because you cannot meet the expectations of others!? Do they meet all your expectations? Do you also indulge in comparing yourself with others? No wonder their words and ringing repeatedly on your ears! Are you also trying to tell me that nobody at all has ever said anything nice about you ever? Or is it that these memories never come to the forefront, only the negative memories come into your consciousness? Surely you can see that you have become your own worst enemy? Surely if you were to evaluate yourself more realistically you would find that you are indeed a very unique person, special in your own way! That just because others cant see it does not mean that they are right! You are your own best judge! Everyone is limited in their lives by their own beliefs and expectations, do not allow the limitations of others to limit you. We are all limited and ignorant in our own peculiar ways. Only God is unlimited, only God knows enough to caste judgement on others. Its good that you were able to ask this question. The view points of others are always good to hear, but remember, they are only view points of limited minds.
