Think this happens to some of us who're in dysfunctional families.
do take note :)

The Hero, who is usually the oldest child, is characteristically over-responsible and an over-achiever. The Hero allows the family to be reassured it is doing well, as it can always look to the achievements of the oldest son or daughter as a source of pride and esteem. While the Hero may excel in school, be a leader on the football team or a cheerleader, or obtain well-paying employment, inwardly he or she is suffering from painful feelings of inadequacy and guilt, as nothing he or she does is good enough to heal his family's pain. The Hero's compulsive drive to succeed may in turn lead to stress-related illness, and compulsive over-working. The Hero's qualities of appeasement, helpfulness and nurturing of his or her parents may cause others outside the family to remark upon the child's good character, and obtains him or her much positive attention. But inwardly, the Hero feels isolated, unable to express his or her true feelings or to experience intimate relationship, and is often out of touch with his or her own sources of spirituality.
