I have been an atheist for some time and I recently realized something that I am curious about. Resulting from depression I have come to see that through resenting myself I create distance with those around me. At the same time I have no purpose to a creator (being an atheist) to live and life seems to become bleak. I began to wonder and feel that the more I begin again to care about people the more I realize how essential they are to an atheist life. When caring about people we find our God or purpose so to speak. Do philosophers say anything about how without God you must care about people to feel like life has purpose beyond hedonism? Any expansion to my question is fine since I am pretty hazy due to feeling down these days.
