Nantini, what I understand about Co-dependancy is when your with someone who has a bad habit, like alcoholism and you live your life according to that other person's habit. Also turning a blind eye to a partners issues, allowing them to continue to abuse themselves in some way, which in turn abuses you as well.

It sounds more like your questioning your self worth and if you are a bother to others.
Also the fact that your sensitive to agruing, many people are disturbed by that kind of behavior. Try not to absorb the ill emotions of others, give yourself permission to let certain things pass instead of feeling you have to sit and absorb it.
