Wellness has been defined by the American Psychological Association or APA, a professional body that a huge chunk of psychologists of the world depend on for authentic information on psychology, as 'a dynamic state of physical, mental, and social wellbeing'. World Health Organisation (WHO) defines health as 'a state of complete physical, mental, and social wellbeing and not merely the absence of disease or infirmity (illness)'.
Wellness or wellbeing is a major goal of life. If we go by the above definitions, you feeling comfortable always when you are alone, meditating, working out in gym, going on solo ride etc. and not getting into the social practice of marriage, relationship building etc. will deprive you at least of social wellbeing. But no one can question your choice and you may lead your life as per your preference. On the other hand, if you feel that your beliefs, behaviour, perception etc. do require a review, please consult a psychologist.
