Yes, in two different senses - my fundamental purpose I found in my spiritual faith, and then that works out in my practical day-to-day as creating things, helping people, being in relationship with people. From your description of a pretty solid life & relationships, I'd echo other responses and say that you may need to find a core philosophy, be it spiritual or otherwise. Humanity has struggled with these questions forever, and I think studying the answers those who have came before will be helpful. Intentional development and maintenance of other friendships is very important as well - strong social network is both fulfilling and healthy!
