Oh justlikeyouimagined - I can think of times when happiness resulted from my decision to pursue a particular career (and there was no other person involved). Happiness doesn't depend on another person. Or happiness was my experience when making art. Get involved in some activities that you find interesting. And read about
happiness and positive psychology (Martin Seligman - well-known psychologist). Get yourself out of that rut. Notice. Appreciate. Enjoy.
