about this, at very least you should actively explore it. It doesn't matter who you are and what you do, if you dread to go to work every day, it is definitely time to think about a job change or career change. Being happy is a process not an end result. If you enjoy doing something, I'm sure that you will feel good about it (=happy).
I always and truly believe that the best memory in a person's mind is the things that he/she truly enjoys doing and is passinate about.
