There is difference between looking and starring. Looking into some one’s eyes, while talking to him/her, is desirable. Difference lies in blinking. If you can manage to talk to someone without looking to their face then why can’t you manage to blink in-between? It is a matter of practice. You have negative self-image because of your complexion and other people’s comment. You have to build up positive image for yourself by accepting the facts which you cannot change. Once you have positive self-image your social phobia and depressed feelings will start getting better.
